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.

A gangster who will glom on to whatever gang is in power, or who will join a gang and help out in a rumble in return for favors. This dude belongs to any gang that is winning, or that will give him a piece of the action. Loyal to no one but himself.

Paco is such a gangstitute; last week it was the Crips, now he's bangin' with the Bloods!
