After spending many pointless hours studying trivial things such as math. Andrew decided he needed to major in something worth his time. So he became a Brofessor.
A close, trusted, male friend who also provides excellent advice. From "bro" - a close male friend and "professor" - someone who is an expert in some topic.
a professional bro. This is a person who excels in party related activity with a professional style. They are good at all things party: i.e. drinking, smoking, dancing, talking to the opposite sex, getting out of situations, etc.
We were down to one cup in our beerpong game and Brad just walked up, looked at the cup, and sank it in one shot. A true brofessional.
