ONG is an acronym that means “on God”. In other words, it means “I swear” or “I swear to God”.
When someone posts ONG on social media platforms such as Snapchat, TikTok or Twitter, it means that they want to express their honesty.
This slang phrase is popular among younger Internet users. It is similar to saying “no cap”.
For example:
“This movie is great, ong.”
This basically translates into “I swear to God, this movie is great.”
As you can see, they are trying to underline the fact that they are being honest. In other words, they really do like the movie. They are not lying or being sarcastic about it.

In this case, the person is basically saying, “I swear, I didn’t know that!”
What does it mean when someone replies with ONG?
If someone replies to you with “ONG”, then it means that they strongly agree with you.
For example, if you say “I hate fake people” and someone replies with “ong”, then it means that they are agreeing with your statement.
It is another way of saying “you’re not wrong.”
