Someone who has surpassed the levels of Jerk, Asshole, Douche-bag and Motherfucker.
Wears baseball caps sideways, spouts meaningless bullshit at everyone, claims he has 'swag', and sleeps with nearly everybody's girlfriend.
Usually has greatly reduced intelligence, and is almost always a hypocrite.
The best ways to deal with a scumbag are:
A: Beat the shit out of him.
B: Make fun of him until he cries, or loses his temper.
C: Say something highly intelligent, forcing him to say something incredibly stupid.
Scumbag: Lol, I fucked your girlfriend last night, you have no sweg, lol.

Guy 1: Did you see that scumbag over there? That dick-wad is wearing his hat sideways!
Guy 2: Yep, definitely a scumbag. Better keep your girlfriend away from him.

Scumbag: Lol, ur gay, no swag, I has #Sweg, fag.
Guy: Hey, leave them alone!
Scumbag: Whatcha gonna do about it?
Guy: *says nothing*
Scumbag: Damn straight.
Guy: Really? I couldn't tell you were.
*everybody laughs*
