Also known as MAD BRO DISEASE, this ailment is fairly common among frat boys or teenagers. A bro will become jealous when his bro starts hanging around with other bros more than him. However, the bro cannot admit these feelings for fear of being called gay, and so instead becomes angry over seemingly pointless things.
Bro 1: "Why is Brosef Stalin over there being such a buzzkill?"

Bro 2: "He's got a bad case of Brovine Spongeform Encephalopathy because Tom is partying with some other bros."

Bro 1: "What a fag."
