Snackblind
Snackblindness occurs after you try to eat the remains of a bag of potato chips or the like, and salt, crumbs or other loose particles, fall from the bag into your eyes causing temporary blindness.
Dude, I was getting down on some Nacho Cheese Doritos the other day and got to the bottom of the bag and there was an epic ball of Dorito dust. I broke the Dorito dust ball into powder, creased the bag down the fold, placed the end in my mouth, and downed it. But not before becoming snackblind!
