A term used to describe a very specific form of
copulation:
During sex, the male penetrates the female, but shifts his body
opposite to hers and, while on all fours with his legs spread in a fashion analogous to a frog, proceeds to bare butt fart directly in her face, thusly mimicking the deep and guttural "ribbit" of a bullfrog. Note that bare
butt farting has been referred to as "the future of sex" in some forward thinking academic circles.
