Pitbull = fighting dog. It got the name I believe from fighting "Pits" where men use to go to see a fight to the death between animals. Grim shit. I suppose the Bull is because it was renowned to be a vicious fighter. If you own something that literally has a name that has a definition of a wild cannon, don't be surprised when you get blown to bits. You have to be full on mega sadistic to even consider a Pitbull a pet. Literally searching "Pitbull Fight" brings up gore shit in the images of a Pitbull biting the neck of an already battered dog with people watching it behind a wall.. it definitely isn't fucking pretty.
