IPA: /ˈkɒkskɒm/
KK: /ˈkɑksˌkɑm/
A person who is overly concerned with their appearance and behaves in a silly or foolish way; also refers to a type of cap worn by jesters that has a distinctive shape.
He acted like a coxcomb, always preening in front of the mirror and showing off his clothes.
Coxcomb → The word originates from the combination of "cox" (from Middle English *cokkescomb*, meaning the comb of a rooster) and "comb" (meaning a tuft or crest). The term originally referred to a man who is vain or conceited, likening him to a rooster with a prominent comb.
Imagine a rooster with its bright, prominent 'comb' — this helps you remember that a 'coxcomb' refers to someone who is vain or overly proud, just like the rooster showing off its crest.
