Fountain Mouth 

The extreme salivation that usually sets in as a precursor to vomiting. Normally occurs during an extreme night of drinking, such as after a harsh shot or one beer bong too many.

I'd had like 13 beers, and I was doin fine. Then, Joe brought me the shot of Jack. As soon as I downed it, the Fountain Mouth kicked in, and I knew I was done. Next stop; Puke City.

When a girl is deepthroating her partner and projectile vomits as a result of her partner's ejaculation.

"This girl was giving me head and puked all over when I came in her throat"
"You just got mouth fountained motherfucker!"

The kid who gets back from pe sweating and puts his entire mouth over the water fountain and no one else drinks from it

"Did you know the kid who puts his entire mouth over the water fountain?" "I'm not drinking from that."
