ONB meaning on Snapchat

On Snapchat, ONB usually stands for ‘On Bro,’ a phrase used to assert sincerity or trustworthiness. It originates from urban vernacular and is mostly used among young people.

When someone says ‘ONB,’ they are expressing that they are telling the truth or that they are serious about what they’re saying. So, if two friends are chatting on Snapchat and one shares an unbelievable story, they might add ‘ONB’ at the end to emphasize that the story is indeed true, not a fabrication.

Alternatively, it can be used to pledge a commitment or make a promise. If a user sends a snap saying, “ONB, I’ll make it to your party tonight,” they’re making a sincere commitment to their friend.

ONB is by no means a term used exclusively on Snapchat, so you may see this pop up in text messages from friends, or in posts on a number of other social media platforms.
