2. Some song by a hobbit from New Hampshire
"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."
When someone excretes semen from their anus in a violent manner, sometimes resembling a rainbows arching shape
dudebro) "The Rainbow In The Dark?"
guy) "EPIC, wasnt it?"
