[...] ALTHOUGH A FOOD ITEM, EGGS ARE SOMETIMES THROWN AT HOUSES, CARS, OR PEOPLE. THIS ACT, KNOWN COMMONLY AS "EGGING" IN THE VARIOUS ENGLISH-SPEAKING COUNTRIES, IS A MINOR FORM OF VANDALISM.

 

[...] EGGS ARE ALSO OFTEN THROWN IN PROTESTS, AS THEY ARE INEXPENSIVE AND NON LETHAL, YET VERY MESSY WHEN BROKEN.
