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.
