FWIW, "git" doesn't have an insulting meaning to most people in the US. "Git" can mean "go" in some US dialects. I would guess that the average person here has no idea that "git" has any kind of negative connotation.

On the other hand, in the US, "gimp" is always either an insult, a derogatory verb, or the open source project.

Git is pretty universally known as referring to an ignorant and unpleasant person.

This is the perfect description for the git command.

No, it's really not. Inside the UK, your statement is true, but inside the US, most people have never heard of this.

Hmm, I'm Australian and it's very well known

Again, Australia and the UK are not like the US, and have different slang.

Where universe fits in the borders of USA.
