mouth fountain

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!"

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.
