Sick, Disgusting, Blob.

Means that someone is a sick disgusting fuck who thinks about sick disgusting things and likes to call random people paedophiles. A SDB will make a joke out of it and they think it's funny when the reality is there are REAL sick paedophiles out in the world. SDB's will get their ass kicked..
Those are some classy people, those SDB's.
