When your doing a girl from behind and you "accedently" slip into her butt. Afterwards tell her to walk it off.
Tom gave Denise the slip in butt last night, now hes sleeping on the couch for the next week.
When you have just raped, destroyed, dissed, BxR'd or had multiple counts of unprotected sex, this is your war cry afterwards.
Damn Rob just got BxR'd, ARF ARF ARF.
