One who wakes up his girlfriend, wife, (or boyfriend, if you dig that kinda thang)in the morning by ramming his cock in her/his ass and screaming "Cock-A-Doodle-Do Beeyotch!!"
Very effective Alarm Cock method! Unless the victim has an extremely loose anus, in which case they will continue sleeping like a baby...well, a baby with a loose anus anyway.
Note: Repeated use may cause adverse reaction and a response of "Cockle-Doodle-Don't Beeyotch" and a bat over the head. For this, I take no responsibility, you Rooster the Dirt at your own risk!!!
