Top definition
A guy that is most likely to go on a killing rampage. Spends much of his time in-doors, is very rational, violent, but rather introverted and humble. Probably has very low self-steem and spends his time viewing and writing definitions on Urban Dictionary, aswell as taking online tests.
I won't make an assumption here, but not to be confounded with loser, the spiteful loner is more fortunate in his life.
