Blowing air out my nose. Similar to "LMAO" used to describe that laugh you do when something is funny but not funny enough to laugh out loud and you just "blow air out my nose".

Baomn is short for blowing air out my nose. Like you know when someone send you something funny but you don't laugh out loud?
Friend: *Sends Meme*
You: Baomn!
Friend: And that means what?
You: I blew air out my nose I didn't laugh out loud.
