A public sex act. A Frosted Waffle occurs when having sex doggie style against a chain link fence and the Receiver's face gets pressed against the fence. The Pitcher promptly ejaculates on the Receiver's face.
"He couldn't stop laughing because what had started out as a hot public encounter ended in my facelooking like a frosted waffle!"
while doing a girl from behind you quickly pull out and cum on her butt. Then quickly grab a tennis racket and start spankin her. When she asks what the hell you are doing you say, thats a frosted belgium waffle
