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 ever recorded is Scott Stapp of the band Creed. Sometimes a case of grungemouth can be so bad that it renders the person's singing incoherent. Pearl Jam's "Yellow Ledbetter" is a good example.

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

Grangemouth Handshake 

The act of anal sex with a radioactive strap on dildo.
Often linked to increased chances of gastrointestinal cancers due to the radiation, and related to Grangemouth due to the grimy industrial town's refinery plant.

"So I found out that I had bum cancer, and thinking back, it was probably because of that Grangemouth Handshake my ex gave me."
