LMOA

An abbreviation normally used for any other conversation, idk.
Basically it means, "lemme massage one's ass".
It also just happens when you misspell LMAO and type this. And now a lot of people will get a different meaning.

"Man this is just so funny."
"I know man, LMOA"
"FACK"
"I mean LMAO"
"You ok bro?"
"What?"
"Nothing"
