ELI5 for cases of tourettes that manifest in cursing, why and how does the brain target the most obscene words, as opposed to just spouting out any random word?

I don't believe there is a definite answer, but the brain does treat obscene words differently to regular language. For example, yelling obscene words when hurt is a universal phenomenon because it actually reduces pain more than yelling regular, acceptable words. 

Presumably, it is more about the catharsis of saying something you're usually unable to say than the word itself.
