the frog
A move in sexual intercourse where the female has positioned herself on top of the male. Her feet and hands are lyed flat on a surface. Her bum moves in an up and down motion, similar to a frog. Extremely under-rated!
Andy: She leaped on top and fucked me like a frog. It was awesome!

Avesh: Yeah bro, my missus frogged me last week. You got to love the frog.
