People that practice ovo vegantarianism are called "eggtarians".
do they only not eat eggs
They eat eggs but not dairy products which is lacto vegantarianism.
o i understand now
The word "ovo" is derived from the Latin word for egg.
i cn see that lol
Sometimes, eggtarians will not eat fertilized eggs such as balut, where the egg has been somewhat developed. 
That sounds really gross
