Top Definition
Internet slang for a person who is both ugly and unintelligent (from the corrupted 'dumb,' 'dum'"combined into one word). To call someone an uglydum insinuates that not only are they ugly, but they are also stupid, however the shortened "dum" softens the blow as most corruptions do, much in the fasion of "stoopid" or "tard"
