A person who is beyond just weird. So weird, that they make up their own words, and try to pass them as real in day- to-day conversations to the point that they start to believe that they are in fact real. Some people may think a weirderer is just a tool.
Anything other than average looks, behavior, personality and all other ways to make you feel weird. Craziness in life will always toss you something that you haven't seen before. It's ok because the weirder the better. You understand it will show up when your not looking.
