Batty flap

Batty means bum and flap usually means the cheeks. Its an urban British slang and for some strange reason others have gotten a different meaning of it. Like how the word faggot which is actually a name for a type of food some how got converted into a nasty insult towards homosexuals by people. Usually it is just used because its funny and more polite than saying arse cheeks.

I will shove that up your batty in a minute. Explanation: I will shove that up your ass - Used when somebody is annoying you with something.
My batty flaps are flapping because I just farted. Explanation: My bum cheeks are shaking from my farting.

Flap Casserole

Flap Casserole...an over-stuffed vagina...when viewed on it's long axis compared to a vertical comparison of the visual reference of lasagna or other meaty layered substance is equal in it relative width, girth, holding capacity, and layered visual appearance is relative to the comparison.

Whoa! her meat sheath was way too big and it looked like a slop box... wait...it looked more like a flap casserole by the time I got there.

"Did you finish?" Well, yeah duh"
