Similar to the shocker. Cross your index and middle, your ring and pinkie and go to town. She'll make that eek eek noise like a dolphin.
Eric: Dude I gave my girl the shocker last night and she was going crazy. Such a good orgasm.
Eric: Yeah you ever heard of it?
Ari: Yeah but its fucking old bro. You gotta do the Double-Headed Dolphin.
Eric: Tell me more....
