Flunch, derived from the similarly-named fast-food chain, "Flunch", is a noun which refers to the object of oral
human expulsion (vomit), or a verb meaning to "to vomit".
The reason this word means "vomit" or "to vomit" is because the restaurant is absolutely revolting, serving up rotten mussels and frozen
sweet products. After dining at the restaurant, if it can be justified as dining, we literally felt
like vomiting, or flunching.
I feel
like I'm gonna flunch.
Somebody flunched behind the door!
Ew, I just stepped in someone's flunch!
That ride is
intense, last time I went on it I flunched.
