A fear of "bros" and bro related concepts, social standings and other impacts on society caused by bros.
My brophobia began to act up after that show last night. There was enough jäger, fist pumping and disrespect towards the vibes of others to end the world!
This one time Barney was walking up to a kid to tell him "I love you" and he was running away screaming from him like he has Barneyphobia. It make sense since people are aware of a big fat purple dinosaur of a pedophile.
