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"
