A red colouring that someone has around their mouth, possibly stained by a drink such as fruit punch.

A quip made by Buffy in Buffy the Vampire Slayer during the first season, regarding a vampire with a blood mustache.
That guy definitely has fruit-punch mouth, although I'm not sure exactly what he drank to get that colouring around his mouth.
