> Torvalds jokingly named it "git" after the slang term, later defining it as "the stupid content tracker".”

I think the better Torvalds quote was when he said "I name all my projects after myself"

I (an American) had only heard the slang version in Holy Grail, and didn't know the slang meaning, and finally am now seeing your comment. Now to lookup the meaning of "manky..."

There appears to be nothing linking Old English "git" with Modern English "git". Also, OEng "git" would've been pronounced more like "yit".
