Frog-smile 

An intimate/sexual act, available for a couple or group that includes a male. To execute a frog-smile, the male and his partner(s) would undress completely, and line up in the position for the game "leap frog," having the male as the hopper. The male would then hop over his partner(s) to drag or rub his genitals along the back area of his party member(s).

Frog Smile 

Involves no penile or vaginal contact. It requires you getting naked. Okay, I lied, it requires penile contact. You do a leapfrog, but you're both naked, and the guy leapfrogs over the girl, and the penis drags all along the backside of the girl.

Last night, we wanted to get it on, but we wanted exercise too, so he gave me a frog smile.

Sonic: My girlfriend Amy really loves it when I frog smile her with my spiky four-headed penis.
Tails: That's disgusting Sonic!
