When you're having sex with a chick that you know doesn't like anal and attempt to sneak it in her ass. She pulls her ass back, shakes her head no and makes sounds like a dolphin, "Ahhkaa Ahhkaa Ahhka"...hence the dolphin tail.
Man, last night I was fucking this hot chick Tina, I attempted to hit the back door and she cock blocked me with a Dolphin Tail!
