look up any word, like plopping:
In reference to the druid balance-spec form, from the popular MMORPG World of Warcraft, is a slang term for a Moonkin who has proven to be very strong in power/crit/and Mana Regen. Usually these Moonkin are found in the top 5 in raids, are near unbeatable in duals and/or PvP, and never seem to run out of mana. Doomkin are meticulously geared, enchanted and gemmed just so with the right spell rotations to make them a very deadly avatar. Also called more commonly Boomkin.
"Dude, have you seen that Doomkin's Armory page? His talent build is sick! He's got double mana regen and subtlety. AND he was 4th on the damage charts!"
