Once you've mastered acid, which you probably did during your formative years, you actually get three more for the price of one. Acid has several spinoff adjectives, of which one of the more grand-sounding is today's word acidulous, almost a dead ringer for the Latin original acidulus. Like its synonyms, acidulous gets some figurative use in expressions like acidulous jokes/debates/one-liners.

If you've ever been embroiled in an imbroglio, you've also participated in a somewhat incestuous characterization because the two words, verb embroil and noun imbroglio are related. Their link is the verb broil, "cook by direct heat." An imbroglio is a confused misunderstanding, which sometimes arises when things heat up.
