A Cookup is what prisoners create out of various food items from the commissary list at their particular jail or prison. Also known as a jail-pizza, a Cookup usually consists of a mixture of squeeze cheese, pulverized doritos or any other spicy style chips, a pickle cut into tiny fragments, a sausage cut into tiny fragments and any other ingredients that would go well in the mixture like hot sauce. Everything is mixed into a paste and it laid over club-crackers, ritz crackers and even can be put between 2 slices of bread like a peanut butter sandwich. The paste can also be heated if the prisoners have access to a heat source. A Cookup is usually made by 2 or more prisoners, each adding their ingredients to the pot. A Cookup is a great way to waste time and serves as a special 4th meal, usually before lights out.
"I've got the chips and a pickle, Tyrone has a sausage and squeeze-cheese. You holding some crackers Vinnie? Aww hell yea son, Let's have a Cookup!"

"What are those 4 prisoners doing huddled around that table with all that food warden?" "They must be doing a Cookup."
