STMF

Sexually Transmitted Man Flu. For those who caught the Rona from a one nighter but don’t want to admit it.

STMA

A whole school full of snakes and hoes. There are about 4 girls in that school that are real and actually care about their friends. All the guys are pussy's and if you get a good guy you are lucky. The amount of popular cliques is fucking crazy.

Billy: Bro do you go to STMA
John: yeah I hate it all the girls are so fake
Billy: Truuuuuuue
