someone who constantly does stupid things or is rather clutzy , acts bizzare, in other words a mal humanoid (not by any medical condition- just personal actions) and can be rather entertaining !!!
that guy is such a mal-toid he tries to impress woman, falls down like an idiot. or someone who makes faces or does body jestures with the hopes of being funny or impressive when in fact he is a mal-toid and looks rather foolish.
