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!!!"
