Internet Creeper 

Typically a man (but let's not generalize) who sits on his computer (probably in a family members basement-apartment which he refers to as his lair) and frequents social networking sites for the sole purpose of creeping innocent internet browsers. Chatroulette is the #1 virtual gathering ground for internet creepers.

Imagine a boring night at home. You log onto chatroulette for shits and giggles and what do you see? Penis aka Internet Creeper.
