Someone who is good looking and has a lot of potential but never uses it. Tries to get everyone to like him/her even though it may come off as annoying and somewhat naive. Generally a laid back person, very kind, and cares for others. He/She is always willing to listen to your problems and try to respond not awkwardly. Try not to upset him/her for they can get angry fast but calm down just as quickly. If you have a Cooper in your life whether a love interest, friend, or even neighbor, consider yourself lucky to have someone as friendly as a Cooper.
Cooper: (verb) also a barrel maker just saying.
