The internet is full of new slang and acronyms, and one that’s popped up among teens and Gen Z is “ONG.” In texting, on TikTok or Snapchat, and in casual chat it often puzzles people. So what is ONG? In today’s slang, “ONG” stands for “On God.” It’s like saying “I swear to God” or “for real” – used to emphasize that you’re telling the truth or strongly agreeing. For example, someone might text, “That movie was awesome, ONG!” meaning “On God, that movie was awesome.” This slangy shorthand has caught on across platforms.
In social media and texting, seeing ONG signals agreement or surprise. It’s a popular TikTok and Snapchat term: if you read “what does ong mean on TikTok”, the answer is still “on God.” Dictionary.com notes that ONG is an abbreviation for “on God,” used to express honesty or strong emotion. FindMyKids (a parenting site) similarly explains “ONG” means “On God,” a phrase now often shortened on social media. Teens use it like “Ong, that’s crazy!” to agree or show astonishment. (There are more examples in the FAQ of slang sites: for instance, “If you smart at math I hate you ong” means “I swear I hate you”.)
On TikTok, “ong” really took off around 2019. Many viral videos and comments use it to amplify truth or hype. As one source notes, TikTok is a hub for this slang, with “on god” responses all over comment sections. People might upload a funny clip and see comments like “ONG lol 😂” or use it in duet reactions. Likewise, in text messages and chats, “ong” (often typed in all caps) replaces longer phrases. If a friend tells you some unbelievable story, you might reply “Ong, no way!” to say “I swear, that’s true.” In all these cases, context (excitement, disbelief, agreement) makes it clear that “ong” means “on God” and not a typo for something else.
On Snapchat, “ONG” shows up in similar ways. Since Snapchat is about quick snaps and chat, these brief acronyms fit right in. For example, if someone posts a hilarious photo or story, a friend might reply, “ONG, that’s hilarious!” to express strong approval. As WolfGlobal explains, seeing “ONG” in a Snap simply means the sender is really serious about what they’re saying – basically “on God”. One blog sums it up: “When you see ‘ONG’ popping up like dandelions … on Snapchat … in the realm of Snapchat lingo, ‘ONG’ basically shouts ‘On God.’”. In short, on Snapchat and other messaging apps, ONG = “I swear,” so use it to pledge something is real or to hype up a story.
Urban Dictionary Definition
If you look up “ong” on Urban Dictionary (the user-generated slang dictionary), you’ll find the same idea. Urban Dictionary entries define ONG as an abbreviation for “On God,” meaning you strongly agree with or believe something. For example, one UD definition says: “Abbreviation for ‘On God’ meaning to heavily agree to something, and show that agreement by mentioning the life of God.”. (UD even notes some people use “ONG” by mistake instead of “OMG,” but most entries focus on the “on God” meaning.) There are a few other UD meanings – one lists “ong” as slang for something very good – but these are not mainstream. The takeaway is that Urban Dictionary confirms what others say: “ong” is slang for “on God,” used to emphasize truth or agreement.
Meanings in Other Languages
“ONG” also appears outside English, but with different meanings. In Spanish, ONG is simply the abbreviation for “organización no gubernamental,” which translates to non-governmental organization (NGO). In fact, AcronymFinder notes “ONG stands for Organización No Gubernamental (Spanish: Non-Governmental Organization)”. Similarly, in French, ONG stands for “organisation non gouvernementale” – again meaning NGO. (Many Romance languages use ONG this way: e.g. Portuguese “Organização Não-Governamental.”) So if you see ONG in a European or Latin American context, it’s probably talking about NGOs, not slang.
By contrast, Chinese doesn’t use ONG as an acronym. You won’t find “ONG” on signs or official terms in China. However, “Ong” (written same letters) can be a Chinese surname in romanization. For example, Wikipedia explains “Ong is a Hokkien romanization of several Chinese surnames: 王 (Wáng in Mandarin), 汪 (Wāng), 黃 (Huáng), and 翁 (Wēng)”. In other words, if you meet someone named Ong in a Chinese context, it’s likely their family name (just as Wang or Huang). Summary: in Spanish or French, ONG means “NGO,” while in Chinese contexts Ong is usually just a name.

Medical Context
Outside of slang and language, “ONG” has a meaning in medicine. In medical terminology, “ONG” most often abbreviates “Optic Nerve Glioma.” According to a radiology text, “Optic nerve glioma (ONG) is a type of juvenile pilocytic astrocytoma (grade 1 astrocytoma) that occurs more commonly in children and young adults.”. In plain terms, an optic nerve glioma is a usually benign tumor affecting the nerve that connects the eye to the brain. It’s a specific disease, not a general term – so if a doctor writes “ONG” on a chart, they likely mean this tumor. (As a note, some medical acronym lists also include “ONG” for things like Orthodontic National Group – an association name – but the clinical usage is optic nerve glioma.)
Other Acronyms
“ONG” can show up as an acronym in various fields (unrelated to its slang meaning). Here are some examples:
- Non-Governmental Organization: As mentioned, in many languages ONG is the acronym for NGOs.
- Oil & Natural Gas (sector): In energy industry contexts, ONG sometimes abbreviates “Oil and Natural Gas.” For example, the U.S. Dept. of Energy refers to an Oil and Natural Gas Subsector Coordinating Council (ONG SCC).
- Orthodontic National Group: In a list of medical organization abbreviations, ONG stands for “Orthodontic National Group” (a professional association).
- Optical Network Gateway: In tech/telecom lingo, ONG can mean “Optical Network Gateway”.
- (Other examples include Ohio National Guard, Oklahoma Natural Gas (a utility), etc., but these are less common.)
Each acronym depends on context: a government agency or company might use ONG for something industry-specific. But remember, none of these have anything to do with the slang meaning – they just happen to use the same three letters.

Table: Summary of ONG meanings by context. Each entry above is cited from sources.
Overall, the most common meaning of “ONG” today is “On God.” In Gen Z slang and on TikTok/Snapchat, it’s a way to emphasize honesty or agreement. But as the table shows, “ONG” can mean very different things in other contexts – from “non-governmental organization” overseas to a specific medical tumor in healthcare. The key is context: look at who’s using it. If a teenager says “Ong!” in a chat, they almost certainly mean “On God.” If you see ONG in a news article or government site, it’s probably “organisation non gouvernementale” (NGO). And in a doctor’s office, it could be shorthand for optic nerve glioma.
By keeping these contexts in mind, you can decode “ONG” no matter where you see it. Whether you’re chatting with friends or reading global news, now you know: “Ong” usually means “On God!” (I promise).
