Pokemon Denial

When something is labeled as "uncool" and people suddenly pretend they don't know anything about it because they think it will make them look bad by association. Coined for people who deny knowing the names of ANY Pokemon, even if they spent several years of their childhood memorizing every single one from the first games.

Alternatively, can be used to describe someone who makes fun of someone else for knowing something that they themselves know, but would not admit to because it's uncool.

Ex: When you use a pokeball in Super Smash Bros, say the name of the Pokemon out loud and your friends make fun of you for knowing it (even if it says its own name in the game).

I usually play as Charizard in Brawl.
Uh... Which one is Charizard again?
Dude, we used to play Red and Blue together EVERY DAY. I think you're in Pokemon Denial.
