Poncy little pretty-boy who thinks that his virginity makes him superior to all other life forms.
Brandon, quit acting like a loinworm or no one will want to be your friend!

Superior internet cool guy from the somethingawful.com forums who flirts with late night drunks and meth addicts, moderators, and other sluts and dudes because they represent the internet elite, at least to themselves. Makes a point of starting gossip about others, circle-jerking, and trolling. His real hangup is that he dated some fat chick once, and he can't forget how badly she e-dumped him. This burn, which happened at least two years ago, prompts his constant anger toward others who like her or knew her. He still degrades her old friends, husband, etc. He thinks that he is outstandingly funny but in short is just another internet nerd who has nothing better to do in in his life but post on some internet forums and pretend he's better than all the rest.
Hi, I am loinworm? I am the best thing that ever happened to the internet. If you don't agree, I'll hate you too!

Holy fucking shit Ricky, get a hammer I think I've got the loinworms!
