I almost never use foul language in its vanilla form when i actually say them. They are almost always given some type of prefix or suffix. Sometimes another cuss, sometimes not. My favorite one to tack stuff onto is probably **** though, but **** gets some nice results too with the always good K sound.

Edit: Though it isn’t as foul of a word, “Turdburgler” is one of my favorite insults this past month or so. The base word made Carlins list, so its enough of a cuss for me.
