Someone who, like me, is completely, totally obsessed with Pokemon. Usually own at least three Pokemon games, and numerous plushes, collectables, trading cards, and paraphanailia. Refers to Pikachu when talking about renewable energy sources. Often claims girl/boyfriend to be Misty/Ash Ketchum.

Guy One- Yeah, the PokeManiac.

Guy Two- Oh, that's ________.

Get the PokeManiac mug.
A variation of the many trainers one must battle in Pokemon Red/Blue/Green. They look like nerdy guys and often possess quite formidable pokemon.
Ash: Summoned Blastoise
Pokemaniac 5: Summoned Nidoking
Ash: Blastoise used bubblebeam
Pokemaniac 5: Nidoking used thrash
Ash: Blastoise used Headbutt
Pokemaniac 5: Nidoking used trash...Nidoking's attack missed!
Ash: Blastoise used ice beam
Nidoking fainted!
Ash received $4290, Blastoise gained 1203 exp.
Pokemaniac 5: Oh no! I can't believe i lost!
