I must admit, outside of Munchkin, I haven't heard ANY of these terms before for gaming. I don't even know what the hell Pokemon is (aside from it being a card game or something).
But I wouldn't be sad to see Munchkin go - it is a term devoid of all real meaning anyway, beyond being used as an insult to someone who uses a different gaming style than a game where reaching 12th level, after 120 nights of gaming, you finally manage to get that rusty dagger+1 as your first magic item (in the whole party) - and you also manage to locate some clothes, after having to run around naked, with no equipment, for the past 6 levels.
