Something hugely unpleasant. Exactly as unpleasant as it sounds.
A psychopath who collects knives - just ordinary shitty big sharp knives - beats people up, kickes them in the head after they've fallen on the ground, then chases after them with four of his knives - two in each hand, throws Ventolin inhailers at people, throws wood-working planes at people, stabs them with blunt rusty old screw drivers, threatens them, and then makes up stories about how it was actually his victim who did all of that to him.
Don't SRF me!
Thing that closet homosexuals do, however it's something that also goes along with the following attributes/behaviours:
-Being violent with people.
-Kicking them in the head while they are lying on the ground.
-Threatening to kill them.
-Chasing after them with knives.
-Lying about who threatened whom.
-Lying in general.
-Kicking people for no apparent reason.
Stop SRF-ing, and start being a decent individual.
