a loser with the name of Louis
If you carry around a graphing calculator in your pocket and your name is Louis, you may be considered a Louiser.

A waste of life. this type of person loves to brag about sexual encounters that they will probably never have. This type of person loves to gossip. This type of person will most likely be 40 and single and live with their parents.
I wish i wasn't such a louiser back in college. Now no girl will go out with me
