look up any word, like ratchet:
A chip dump is the action of dumping the last little bit of a bag of chips into one's mouth for the purpose of finishing off the bag without having to use one's hands to pick up the tiny chip fragments. Chip fragments are considered by some to be the most sought after part of the chip eating experience.
Guy: Hey can you pass the chips?

Girl: *passes chip bag*

Guy: *commences chip dump*

Girl: *shakes head*
