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.
