Slamman 

The scourge of GTAForums.com, acts like a hobo and is a greasy long-haired slob that sits around on his PC creating useless topics and making useless posts on GTAForums. He is one of the least respected people over there and is generally treated as the village idiot.

Slamman: I had to sell my PSP to pay the rent.
GTAForums Member: Good for you, no one cares.
