when bro-ro gets angry with the kids in his class and screams so loud that he loses his voice and the veins come out of his neck. the vibrations from these bromoans can be heard for miles and have been known to register on the rickter scale causing 2.3 level earthquakes. this type of bromaon can be considered to be pretty fricken hilarious.
