That guy who makes us shake our head in disbelief but at the same time makes us feel better about ourselves since we are not him.
"Jake just spent $80 buying those hot chick shots and then they walked off with those other guys!" "He's such a tool!"

(n.) - an individual who willingly changes his or her behavior for personal gain or profit. In this context, a tool is similar to a poser, with one important distinction. Because a tool does not consider his actions beyond rudimentary cost/benefit analysis, he or she will often be co-opted by corporations or powerful interest groups to support the lame or corrupt positions held by these organizations. A tool therefore, is quite literally an instrument of the man.
Mitt Romney is a tool.

An individual who behaves in their own self interest rather than adhering to a set of beliefs or morals. Someone who will act as though to seek approval on the outside, but is actually quite vain and selfish. Men of this variety tend to cheat on their girlfriends. Women tend to use men to obtain free drinks.
