Llama Shanker
The sexual act where one person stretches out their neck (impersonating a llama), spits in their partners eyes until he or she is blind. Then the blind partner proceeds to find (blindly) the opposite sexual mate's genitalia and shank (also known as "stab") it with a carrot.
I'm buying some carrots, not for the Vitamin C, but so that Marie and I can do the Llama Shanker tonight.
