It’s a word used instead of lmao or Lol .BATMN stands for “Blew Air Through My Nose.”
Most people don’t laugh when they read or see something funny the just do a little chuckle or a blow of air through their nose hay didn’t exactly turn in to a laugh. It’s very accurate compared to lmao and lol.
Sends funny meme

"Blew air through my nose" used when something is said funny. It is a new trend that is related to "lol, lmao, lmfao, ROFL" and all types of shit yall say when something is funny, hell if I know what yall use nowadays. Also it kinda looks like the name Batman.
"Don't let this distract you from the fact that Mr. Krabs sold spongebob's soul for 62 cents."
"BATMN!!"
"BATMN? are you trying to say Batman with your non spelling ass"
"Nah bro I meant BATMN aka Blew air through my nose"
"Ohh.... Well that's how we usually breathe... Sometimes I pray for this generation"
