A man/woman who acts very annoying and makes loud noises when a alarm clock goes off.
“Jeez that guys is a real Alarm Cock in the morning”
A typical alarm clock with a slight surprise. When the alarm cock goes off a slightly limp dildo is smacked into your forehead violently. Usually leaving a slight veiny imprint or possibly a bruise depending on your model of the alarm cock.
Tiffany: "Whats that oddly veiny bruise on your forehead, Bruce?"
Bruce: "Oh that? I got the new Alarm Cock 3000."
Tiffany: "Damn I should upgrade mine, I have last years model."
The act of waking up your girlfriend or wife for morning sex before her alarm clock goes off.
I woke up my wife with the "Alarm Cock" for a quicky before she got up to get ready for work.
