Who is Maurice from Bloodsucking Fiends and what is their importance?

Maurice is a gay man who works at the makeup counter in the store where Jody buys her little black dress. Jody gets her face done, and Maurice tells her she's a "Winter Woman." Maurice, who is in league with the saleswoman Jody offended, purposefully makes her up to look both trampy and gothic. Jody embraces the vampiric look.
