On Everything2, an easter egg is a type of item users can collect which can be "thrown" at other users in the chatterbox using one of a series of easter egg commands.

The basic egg command is "/egg", and is used thusly:

/egg mauler 
You EGGS MAULER

A user who is "egged" in this manner receives 3 GP, and the thrower has their total collection of easter eggs reduced by one.

There are also an unknown amount of additional "secret" egg commands, but you will have to discover those for yourself!

The easter eggs first appeared on Everything2 as part of an Easter-themed April Fools Day event orchestrated by kthejoker on April 1, 2007 (a bizarre day which also featured images of the Easter Bunny randomly appearing across the site). Although initially only intended to be part of this one-time event, the easter eggs proved so popular with users that they were allowed to remain as a permanent part of the site.
