A fork chip is one of the crisy lil chips that stayed in the fryer too damm long.
However as they are crispier and more solid than the standard chip you can use the lil fella as a fork, stabbing it into its softer counter parts and eating them, while getting limited grease on ya fingers!
Messy Friend: Man i got mayo all over my flippin fingers, how come yours are so clean!?!?
Me: well my less informed chum, thats because im using a Fork Chip
