Similar to the shocker, in the insertion of the index and middle fingers into a girl's vag and a pinky in the ass (two in the blood one in the mud.) The difference lies in the fact that the two front fingers are twisted like an electrical chord and the thumb/dorsal fin is used for clitoral stimulation. The desired result is a woman's screech similar to the call of a dolphin (errhhaaa! errhhaaa!)
girl: errhhaaa! errhhaaa! errhhaaa!
guy: That's a mutha fuckin' electric dolphin for ya ass.
