Since I use this term often, I thought it prudent to include here.
git (git): / git /
(1) a foolish, contemptible, worthless, troublesome, unpleasant, or annoying person
[British slang. A variation of ‘get’ used in Scotland meaning “brat” and implying illegitimacy.]
Usage: I don’t seem to have any problem making myself look like a clueless git from time to time.
