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- hey, y'know that nerd's name over there?
Guy Two- The one withthe Pokemon deco all over her textbooks?
Guy One- Yeah, the PokeManiac.
Usually used by adults, either to annoy their kids or to make the kids turn of their game boy. There is also digiman, which is another addition to the '-man' parent language.
Pokeman is where a boy with crossed eyes runs around with a yellow mouse. Sometimes he is in the company of a blue blob or something but for the most parts he's yelling- "I'm gonna catch all youz pokeman!"
