An abbreviation of "scrap chips", scrips are the loose french fries that you find at the bottom of a McDonalds paper bag.
It is important to note that french fries are not defined as scrips until they have fallen out of the fries bag/box, and make their way between the burgers down to the base of the paper bag.
Scrips only become visible after you remove all other items from the bag. Therefore, they are usually eaten after you have finished your burger and french fries. While this means they are normally cooler in temperature than normal french fries, scrips provide the perfect ending to a McDonalds meal, especially when dipped into your chocolate thickshake.
"Oooh look !! Scrips !! Bonus !!"
