Git is a fairly mild insult though, roughly equivalent to calling someone annoying. I'm sure at least a few of us have thought Git (the tool) to be aptly named, from time to time.

And here I thought it was redneck for "get" like that's where ya git yer code from.

Linus once quipped "I'm an egotistical bastard, and I name all my projects after myself. First 'Linux', now 'git'."

Is "fanny" an insult at all?

Yes, in Britain it is, you fanny.

That one is specifically British though. Or perhaps even just English, I can't imagine a Scottish person using it.

So what? The answer to the question is still yes.

Damn! That was fannier than I expected. Lmao.

It was also equivalent to "bro" in the late 90s, at least in some circles in the US.
