Surprisingly teshticle has no connection with the word testicle - therefore it is not a rude word. Teshticle is a word used to refer to a geeky person - specifically someone who played lots of video games, watches childrens tv shows and spends large amounts of time searching for weird things on the internet.
That girl is such a teshticle!
