1. a fetish with vomit (and sexual interaction) 2. fucking someone so hard they throw up 3. a girl's gag reaction causing her to vomit while giving oral sex.
Tami was giving me head and then all of a sudden she pulled an upchuckfuck
I heard Tom likes a good upchuckfuck...ewww
I was giving it to her so hard, it turned into an upchuckfuck!
