Any giant penis that should never see the light of day but somehow always does when the owner gets drunk.

Like most evil, shadow dwelling creatures, the trouser troll is ugly and smells of rotten death.

You always know the trouser troll is there and are afraid to approach the area where it lives.
"Oh my god, last night Aaron got drunk and I saw his trouser troll!!!"

"Really? And you didn't turn to stone??"

Get the Trouser Troll mug.
A woman who is looking to get in your pants.
One who trolls for trouser snake.
I picked up a trouser troll at the club last night and woke up at a motel in a bathtub of ice with a missing kidney.
