a man who places a glow bracelet around his penis and testicles at festivals in order to be seen at night and to be identified by his friends and fellow glow cockers.
Did you see the glow cockers dancing at the Firewater Lounge last night? I think that's worse than shirt cocking.

A term to use in place of the phrase "mother fucker," when:

1) Saying "mother fucker" gets old
2) When the situation requires a PG rated euphemism for mother fucker
3) When you accidentally hit your head on a blunt object (cabinet, etc)
4) for fun

The name given to a man who carried out a series of attacks in Sheffield, England in the summer of 1988. These attacks involved him going door to door in residential areas throughout the city with a male chicken hidden discretely under his coat. Upon finding an unlocked door, he would forcefully thrust the "Mad Cock" on his victims on the other side of the door. Such attacks were marked with a card thrown into the fray with the words inscribed: "You've been Cocked by the Mad Cocker".
After my aunt was cocked by the Mad Cocker, she had to spend 6 weeks in nuthouse receiving daily electroshock therapy. She's still never fully recovered.
