The patato chip is the art of one best friend walking in on another best friend while he is on his honey moon having sex. THe friend that walked in commences to ask if the friend that is having sex can "pass the chips". If the friend has no chips, the other friend has the option of peeing on the two passionate lovers, or kicking the friend in the nads at the point of climax.
(John walks in on Micah having sex)
John: Hey Micah, can you pass the chips.
Micah: Dude, here. You bastard.
