This rare ghost apperars while: Watching pornography in bed, looking at a poster of a hot chick while in bed and if you really need to piss while still in bed.

It's your fucking dick gone hard while your in bed.
Man 1- I was watching some hot porn the other day in bed, and I got the biggest fucking sheet ghost.

Man 2- Dude, why the fuck did you have to tell me?

Man 1- Cause it's for the urban ditionary example.

Man 2- Oh, so thats why my parents named me Man 2.

Man 1-What parents?
