M.O.F.S.
A woman who takes a drag like it's a war and doesn't back down.
My friend is a M. O. F. S. She smokes like she's fighting a dragon.
My aunt is a M. O. F. S. She smokes so hard, she could light up a whole room.
My coworker is a M. O. F. S. She takes a drag and stares at you like you’re the enemy.
