from today's Word a Day:

coxcomb (KOKS-kom) noun

A conceited man excessively interested in his appearance and dress;
a fop.

[A variant of cock's comb (a rooster's crest).]

Jesters in medieval courts wore a cap with red strips like those in
a rooster's crest. From there the sense of the term extended to a
vain, pretentious dandy. Today we would describe him as metrosexual.

Court jester, to Wilde dandy, to Beckam metrosexual? Hmmm. What's missing is the wit.
