Get the chump mug.
Generally, a person who lacks common sense, street smarts and a sense of self. A slow witted person. One who does not know the ways of the world. One who does not know their ass from a hole in the ground. Easily manipulated & taken advantage of. Usually operates in a field that is way above their skill-level. Incompetent. An embarrassment. Essentially a tool; a useful idiot. The chump usually thinks he is cool and suffers from over-confidence; but is just a player and is being fooled before s/he knows it.
1. Tom Cruise is the classic definition of a chump. He thinks he is smart and cool, but Alas; falls into the barrel of laughs that is moronic, delusional Scientology.

2. Most Polish people from the country of Poland qualify as chumps. (Don't believe me? Hopefully find out for yourself one day. Such pathetic immigrants I have to deal with.)
