This rare species of the male version of a fangirl is hard to find. Fangirls will do anything to meet a fanboy in real life. Like fangirls, fanboys obsess over actors and fictional characters. They are incapable of squeeling so they awkwardly stare.
Fanboy: "CRAP there's a fangirl! RUN!"
Fangirl: *attacks fanboy and aggressively flirts with him* "Wow it's so weird to find you out in the wild"

"You were a Heat fan last year but Warriors this year? You're such a fanboy."
bandwagon fan

Radlin, the greatest of the Dark and Light FAnboys. Ingores common logic for the greater purpose of making people think that DnL will be a good game.
Radlin almost killed himself when he was kicked out of the DnL beta for breaking NDA.

A term used by losers of an argument when they have no valid option other than to try and discredit and dismiss their detractors through personal attacks. See Nazi, Racist, etc.
