Pronounced "hacksore."
Generally meaning one who hacks fairly well and often.
Can be used when someone is of 1337 (
leet (elite)) skill in a game or when someone is incredibly
lucky and therefore must have cheated or "hacked."
When being called a h4x0r, it is usually taken as a compliment by gamers unless used in the middle of a
cuss-filled rant about how that should not happened.
