The fat kid salute occurs when a person lifts a bag (chips, candy, popcorn, etc.) above their head so as to dump the remaining crumbs into their mouth. The salute is something that all fat kids recognize and should be used to unite fat kids everywhere.
I gave a good old fat kid salute to finish off my family size bag of Cool Ranch Doritos.
