Ride the dolphin 

masturbating. similar to jacking off, whacking off, flicking the bean, chocking the chicken, spanking the monkey, slapping the ham, fighting with your purple headed yogurt slinger, and tug of war with cyclops.

"Sorry i had to ride the dolphin. Saw this really hot chick."
"Dude thats nasty!"
