A maxcapper is someone who can top any story, anything you say you did he says he did it first, or he did it better, or his was bigger, or he made more money, or he caught the bigger fish. Usually a liar, and eager to start meaningless arguments. alt. Captain Max or Mr. MaxThat
That maxcapper told me he won two oscars when he heard I won a medal for eight years' service to the community. Who is he, Captain Max? Mr. Maxthat? Sir max a lot?
