Endearing term for a homosexual who sells his body for menial goods or favors. Uses the motto "This crack's for hire, even if we're just dancing in the dark."
I told that fucka that I wasn't a buttcrack and to keep his damn chips, but he kept propositioning me.
A person who is very proficient in the art of the deadly fart, it may be silent, it may be noisy, but one always knows for a fact that it will be stinky, it will clear the room, and sicken the occupants with it's ghastly odor, this term was coined by the fact that some of these odoious folk have actually cracked the skin around the butthole by releasing their poisonous gas.
