An idiot who hates any Pokémon Games made after Yellow, without giving any actual reason. Genwunners continuously voice their opinion in the jerkiest way possible, while refusing to accept the fact that normal people have their own opinions.
Genwunner: How can you stand White?
Normal person: It's actually really good, you should try...
Genwunner: No, you idiot!
Normal person: It's actually really good, you should try...
Genwunner: No, you idiot!

An individual who refuses to accept that Pokemon generations after the first Generation, Red, Blue, and Yellow (or to some extremists, not even Yellow), is enjoyable or has good designs of Pokemon. They are generally very violent and close-minded about their views regardless of not playing any Pokemon games since Red and Blue.
