What is Bununch?
1.
noun
pronounced: buh-NUNCH
used to describe the appearance of a vagina as being similar to the appearance of a side-view of a roast beef sandwhich. The comparison is based on the fleshy, multi-layered folds existing in both roast beef sandwiches and vaginas.
"Look at your sandwich, it has total bununch!"
"Yeah, looks just like your mom's bununch last night!"
