When a male wakes up his partner in the morning by ramming them in the rear with his cock and screaming "Cock-A-Doodle-Doo Beyotch!"

Does not work so well on a sleeper with an unusually loose anus, in which case they will continue to sleep like a baby....well...a baby with a loose anus anyway.

Warning: Repeated use may invoke adverse reactions from sleeper; including but not limited to; a bat over the head followed by an emphatic "Cock-A-Doodle-Don't MuthaFucka!"
"That bitch kept hitting the snooze button, so I had to wake her up with the Alarm Cock!"

your wife/girlfriend/booty call asks you to wake her up the next morning (or you decide it's time for her to get up), and when the time comes you silently perch over her, masturbating furiously until you bust in her face. also known as the wank-up call.
