I gave my givefriend a Detroit Nightmare last night. She was really pissed, but it was fun.

Get the Detroit Nightmare mug.
The Detroit Nightmares are a club in Detroit. Sort of like a Biker Club. In example, "That Guy's a Detroit Nightmare, just be cool with him and he'll do the same towards you.
He's with The Detroit Nightmares. Respect him and he'll do the same towards you. But if you step on his toes, He'll cut your Fu*king feet off.
