look up any word, like dirty sanchez:
When a woman passes gas out of her anus and the air bubble goes up her vagina.
I thought I had to fart but it ended up as a flotch.

I will never wear those jeans again. I was flotching all night long.

Fat crotch. The area of a male or female's flabby torso that connects to the crotch area to form a basketball-like appendage.
Mr. Joe's flotch hit me in face as he turned to hand me my graded paper.
