Grunge mouth

When a singer intentionally changes the way he phrases or sings his words, most prevalent in grunge music. (i.e. pronouncing "here" like "hurr") The worst case of grunge mouth has to be Scott Stapp of the band Creed. Sometimes a case of grungemouth can be so bad that it renders the person incoherent. Pearl Jam's "Yellow Ledbetter" is a good example. :D

Jelly Mouth

When you have vigorous oral sex with your girlfriend immediately after she comes done at the dentist and is all mouth numbed from Novocain. Reduction in her gag response allows for more gratifying deep throat action and she cannot easily identify your point of orgasm so you can easily throat one down.
I’ll be late today. I’m taking Rachel to the dentist. She can’t go alone? She can but I’m working that jelly mouth as soon as she’s in the car. Ain’t missing that brooohhh.
