From dictionary.com for you uneducated heathen:
git
n : a person who is deemed to be despicable or contemptible; "only a rotter would do that"; "kill the rat"; "throw the bum out"; "you cowardly little pukes!"; "the British call a contemptible person a `git'" [syn: rotter, dirty dog, rat, skunk, stinker, stinkpot, bum, puke, crumb, lowlife, scum bag, so-and-so]

My colonial colleagues will understand. Its like one of those marketing campaigns where they mistranslate and call a car the noodle.
IE, for the really slow, Torvald has named this addon the equivilant to "TARD" in many countries.
