Euphemism Buster

Someone uses a euphemism, Last-Second Word Swap or something similar, and someone else blurts out exactly what the first person meant.

It generally comes in two versions: Ditz and Intentional. Ditz version is just the person figuring it out for himself. Intentional being the euphemism is too insulting/obvious or the character simply doesn't care, and so busts the euphemism.

The euphemism may or may not be unusual. Compare and contrast If You Know What I Mean, Don't Explain the Joke.
