not your girlie friend or boyfriend, but rather your piece on the side. ya'll just hook it up once in awhile in a non-committed type way.
I just broke up with my girliefriend, but at least I still got my piece on the side. I'll sext her a booty call later.

Jack: Naw, that’s just my slam piece of side boob.
