Verb. To remove a prawn's
digestive system during the shell peeling process.
A prawn (or shrimp) will normally shit itself when it realises it has just been thrown into
boiling water or on a barbecue. Therefore after the prawn is cooked, and you peel off the shell, you will find a string of
black stuff running down its back. This can be easily removed by digging the index finger in just behind its head, grabbing the black string-like thing and pulling down towards the tail. This is commonly known as "depooping".
