A word to describe someone who does random crap, just trying to be funny. It may be the jerk at your lunch table, the loud retard in the library, or the little kid that curses on x-box live, point is, there are Meesches everywhere. The best way to defeat a Meesch is to yell loudly "What a Meesch!", while pointing at the Meesch.
Did you see what Sawyer did? Ya I know! What a Meesch!!
