Flapping their gums 

When someone is said to be “flapping their gums” it means that he or she talks a lot about topics he or she doesn't really understand or know about. It also means to say something but not really mean it.

Frank and Joe are always flapping their gums about what it's like to be street hustlers, when they have never even been out of the burbs.

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.

Bustin’ Gums

Head. Sucking dick. Oral copulation of the penis that typically results in the bustin’ of a hot throat oyster from an aggressive skull fucking.

I’ll be bustin’ gums on Rachel tonight.

As soon as I got home the D was in her mouf bustin’ gums.

I was bustin’ gums and popped a sticky oyster. Her eyes watered and she gagged but took it like a champ.
