look up any word, like the eiffel tower:
(pronounced with a hard G)
An person who has a highly irritating effect on others, usually because of the fidgety way they move, but in extreme cases their presence alone causes discomfort.
I couldn't concentrate because that git-rabbit dave was there.

I'm going to go sit with them and be a real git-rabbit.

Go away, don't be such a git-rabbit.
