Beta Rho Greater Omentum. A high class and secret medical society, originated in Upstate New York. Members, also known as "bros", swear their allegiance to the greater omentum. Members have shaved chests, consume tacbros every Tuesday, and gather most weekends at the "frat" for party activities. Pledges must perform a self lobectomy, removing 3.14159265 (pi) ounces of their greater omentum as a sacrifice and sign of loyalty to BPU. Startups of other chapters around the USA are pending.
