You Are Going to Have Egg on Your Face Very Soon 2 June 2009, Cervera de los Montes 12 x 11 x 15 cm Permanent marker on egg carton, half dozen of eggs i To have egg on one's face (idiomatic) means to suffer embarrassment or humiliation; to damage one's reputation. Egging is the act of throwing eggs at houses, cars, or people. Eggs are sometimes thrown at people as a form of protest as they are inexpensive and nonlethal yet at the same time very messy when broken.
