LOL! You're right, and "stupid git" is actually redundant. "GIT" is shorthand for Georgia Institute of Technology, but "git" is defined as follows in Wiktionary:

'Git' is usually used as an insult, more severe than twit but less severe than a true profanity like w*nker or a***hole, and may often be used affectionately between friends. 'Get' can also be used, with a subtle change of meaning. 'You cheeky get!' is slightly less harsh than 'You cheeky git!'.

'Git' is frequently used in conjunction with another word to achieve a more specific meaning. For instance a "smarmy git" refers to a person of a slimy, ingratiating disposition; a "jammy git" would be a person with undeserved luck. The phrase "grumpy old git", denoting a cantankerous old man, is used with particular frequency.

And now that I've beaten that horse to death, there goes my joke, down the rabbit hole. Sigh...

Ummm, thanks for the education. I thought it shorthand of Georgia Tech.

I did not know the word (meaning) before ..... didn’t encounter its use here.
