Dr. Game Grumps's definitions
The frog smile is a sexual act performed by a man and a woman. Both participants must be naked with the woman standing in front of the man. The man then leapfrogs over the woman, dragging his penis and balls across her back and head.
Sonic: My girlfriend Amy really loves it when I frog smile her with my spiky four-headed penis.
Tails: That's disgusting Sonic!
