doomhole
A secondary slot/hole above your original asshole. Sometimes collects dirt and other foreign items. Has been known to suck entire people in at one time. They are natural born defects that some people have. 1 in 1000 are born with them. If controlled and used properly, they can be more than just a useless little hole.
"Is that a second asshole?"
"ITS A FUCKING DOOMHOLE!"
