When a prisoner keysters an extra piece of bread from the chow hall, and eats it in his cell later that night.
Prisoner 1: Gimme yo prison biscuit bitch!!
Prisoner 2: But if I give it to you now, i'll have to give it to you everyday and I won't get my vitamins.

Biscuits perfectly designed for dipping into tea, coffee, hot chocolate or your preferred beverage. Favourites include Digestives, Rich Tea and to a lesser extent Jaffa Cakes (although debate still ensues over whether or not these are actually biscuits. If not then a new category shall be created called 'Dippy Cakes', into which they will fall).
Sam, could ya get some biscuits as you're out?
What kinda biscuits?
Ah any kind of Dippy Biscuits will do.
