A person who makes idiot comments, decisions, and actions. This person can also be
seen wearing ridiculous things. Also, if a person does not fit in, they are a lou. The word lou can be used as a noun, or to describe something or someone. If someone is a lou, they often times don't realize it until they are called
one directly. As a
friend, you should always let your friends know if they are being lous. If there is a lou in the area, call a "lou alert" by notifying others around you. This will keep you
safe from further lou actions.
