A sexual routine involving a coconut, one cooked crawfish, and one living crawfish. While in the missionary position a coconut is broken over the women's head to ensure she is limp for the following, the cooked crawfish is inserted into the anus and the living into the vagina, both are then sucked out broken open, dipped in the coconut milk and eaten. It is a favorite among southern Cajuns and the French.
"You haven't eaten crawfish until you have had the coconut crawdaddy"
Kacey - "Kota, why are your limping"
Kota - "I got Coconut Crawdaddy-ed last night and the live one got a little feisty"
