Half-Pound Prawn Basket

Two or more penetrative entities in one opening (male or female), where at least one such entity is a penis with a tendency to be overly enthusiastic, especially if it's already been hand-breaded. One could say it is plump, juicy and perfectly seasoned. Of the easy peel variety. Boom-boom shrimp and then there was one (ergo, a 1/2 pound). There is fortunately an easy solution, which is to make this a peel-and-eat style basket.

"We were gonna have some fun last night but it turned into a half-pound prawn basket thanks to Minuteman over here, so we had to go the peel-and-eat route. I could do a lot worse."
