look up any word, like mexican microwave:
 
1.
One who selectively chooses only white eggs over brown or other differently colored eggs (including robins eggs, quail eggs and other class Aves varieties). Not to be confused with egg whites which are the common name for the egg albumin which is similarly colored in most eggs. Additionally, Easter eggs albeit differently-colored are often white eggs and like or dislike of artificially colored eggs does not in and of itself endorse eggacism.

Can also be used to describe one who enjoys lasers.
Chris removed all the brown eggs from the fridge and replaced them with white ones. What an eggacist!
