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

Worst purveyors of grunge mouth are Creed, Pearl Jam, early Stone Temple Pilots, most recently heard with band Volbeat.

ratchet mouth 

When you wake up in the morning after a long night of hard core drinking and smoking and you get up and don't brush your teeth

As an example, Giggles woke up from a crazy night of drinking and smoking at a friends house (without brushing her teeth when she woke up). When she woke up she tried talking to her friend, first thing that was said was "damn you have some serious ratchet mouth!"

polish mouth wash 

When a polish man waits to ejaculate or have sex for 46 weeks so his cum is locked loaded and ready, cums into the mouth of a teen male or female large enough to fill a entire mouth because of the back up he endured in his sex life. The technique helps give the teens fresh breath and no cavities.

He Sondra your breath smells great! "Yea my uncle Radis said he was waiting so long to give me some polish mouth wash. I had some this morning from him"

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.
