An umpalumpa Usually called by the sexy chelseas. Is very nice and lucky to have in your life. A dennis is usually sporty. Also is a wild, crazy, fun, weird, handsome person. Can also be the sweetest guy when he really likes someone. The best Dennis's are Assyrian.
I dated a Dennis once and he was AMAZING! To bad it ended...
