https://en.wikipedia.org/wiki/Git#Naming

Torvalds sarcastically quipped about the name _git_ (which means "unpleasant person" in British English slang): "I'm an egotistical bastard, and I name all my projects after myself. First 'Linux', now 'git'."[31][32] The man page describes Git as "the stupid content tracker".[33]

The read-me file of the source code elaborates further:[34]

> "git" can mean anything, depending on your mood.

>

> * Random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.

> * Stupid. Contemptible and despicable. Simple. Take your pick from the dictionary of slang.

> * "Global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.

> * "Goddamn idiotic truckload of sh\*t": when it breaks.

The source code for Git refers to the program as "the information manager from hell".
