Douche Flap

(Not to be confused with actual douche/hygiene-maintenance equipment)

Synonyms: see ass clown, Assclown McDouche

"Sweet fucking Jesus tits! Look at this douche flap cutting me off!" Nice driving asshole!"

"Even though I have higher qualifications, Henry gave the promotion to that fucking douche flap Dave who isn't even here half the time!"
