look up any word, like bukkake:
A combination of the words guffaw and vomit. A combination of laughter and disgust so strong that you actually vomit. Similar to upchuckle, but with the added sensation of actually regurgitating enough to taste it.
The papercut scene in the movie Jackass made me guffomit.
