A bro that bro'ed before all other bros. The prototype for all future bros. Does not know how to get anywhere other than the gym and tanning salon. One cannot bro harder than the protobro. Typically they dwell in Omaha, Nebraska and can be easily distracted by other bros.

A person dissimilar genetically from Homo Sapiens, lacking critical cognitive skills, the ability to learn from mistakes and devoid of any meaningful verbal ability. Should he or she accidentally breed, their progeny will die out within 2 or 3 generations in a fizzle of hyper-Darwinian evolution.
Quit raggin' on poor old Jolene...her daddy was a proto-hominid and the girl can't help the way she is.
