M.O.F.S.
The girl who lights up the room and everyone else's lungs with her cigarette smoke.
My ex is a M. O. F. S. She smoked in my car and my bed. I still smell her in my dreams.
My sister is a M. O. F. S. She smokes so much, she’s got a cough that could knock out a bull.
My neighbor is a M. O. F. S. She smokes in the hallway, and I can't breathe through my nose anymore.
