Pieing is the act of throwing a pie at a person. This can be a political action when the target is an authority figure, politician, or celebrity and can be used as a means of protesting against the target’s political beliefs, or against a perceived flaw — arrogance, hubris — in the target’s character.

The political act of pieing has its origins in the “pie in the face” gag from slapstick comedy (first popularized by movie director Mack Sennett around the year 1914 in his Keystone Cops silent movies). Throwing pies as a comedy staple came into its own in the Laurel & Hardy classic short film, “The Battle of the Century” (1927) which, according to legend, required four thousand pies.
