1. The sexual act where the girl ties the guy to the bed, blind folds him, turns the lights off and tells him he is in for some real kinky sex. She then opens the closet and lets out her gay best friend who goes to work on the guy; Blow jobs & anal. The dude gets off 'cause he has no idea what happened. This is most often initiated by either the worst girlfriend ever, or the best friend any gay dude could ever have.

2. Some song by a hobbit from New Hampshire
"Wow, Edgar's girl friend must really despise him."


"Because she gave him a Rainbow in the Dark last week and then told him about it! He's been in the fetal position ever since."

"But he loves Dio."

"No! Read definition #1!"

"Holy crap, I dated that same chick last Summer! I just thought she was kinky... I suddenly feel ill."
