Fem day 

Flour, Eggs and Milk day. When a person takes it upon themselves to throw a bag of flour, some milk and eggs at someone else - usually as a very extreme prank. The FEM is sometimes encased in a glass jar. The glass jar often inflicts greater pain than the FEM itself.

FEM day did actually happen and resulted in the participants having legal action taken against them. The charges were later dropped.
