The study of the evolution of bros. Starting from Bromo Erectus to Bromo Sapien. The scientists who study Brotology are known as Brotologists. The study is usually conducted by observing bros in their natural habitat, from their dwellings to their mating ground i.e. Clubs, Bars, Parties, and Work, etc.

Guy 2: I think im going to get my Phd in Brotology, i get paid to watch guys party, and watch them have sex with some fine ass bitches.
Guy 1: Damn where do I sign up for that?!
