Gumstitute

A toothless prostitute. While generally of the dirty, nasty meth whore variety, a gumstitute is known for their ability to perform a hot gummy.

Although he felt dirty and nasty after the deed, Carl could not shed himself of his penchant for weekly sessions with the local gumstitute. He just loves a hot gummy.
