A crazy weird loser who likes to sit on the net all day and annoy complete strangers - usually posting racist imagery.
A creeper usually criticises others for faults that apply to him, and which may not apply to his target.
He'll usually be friendless with no job - or homeless, but he'll pretend online that he is popular - even when he is not popular online, and he'll frequently try to convince women that he has lots of money, when he is in fact, bankrupt.
Usual creepers will blackmail people online, or threaten people, or just take random peoples pictures and deface them.
That Sonny was a definite creeper when he abused the internet forum for posting racist pictures.
That Vitale was posting pictures of other forum member's pictures, and member's children's pictures with penises and dildos super-imposed in their mouths - what a creeper!
That Tony has no morals - see as he abuses just about everyone online. Such a creeper!
