You're a bastard - in the strict sense - which is uncommonly used nowadays, other than mischievously - if born out of wedlock. Being brought up by a single parent is a separate matter.

Urban dictionary has a definition for git that is a bit closer to how I've always understood it. See #2: http://www.urbandictionary.com/define.php?term=Git

I misspoke when I implied that all children brought up by single parents are bastards. In any case, my point stands. Github makes children born out of wedlock feel unwelcome and they should change their name.

Git may be a synonym (sort of) for "bastard", but not for all of its meanings. I doubt anybody would link "git" to birth out of wedlock.

(Judging by this particular hoohah though it may be true though that Github might eventually turn out unwelcoming to those fitting definitions #2 or #3 from the above link.)
