Buffalo people are half buffalo, half human. The only known living buffalo people reside in Laconia, NH. They can be easily distinguished from normal people by the large horns protruding from their heads. Buffalo people also tend to have more visible hair than the average human.
People who live in the city of Buffalo are very hairy and have developed horns. This is only to adapt to the large amounts of snow that god shits on them every year. The hair is to keep warm, and the horns are for headbutting as a display of dominance.
People who live in the city Buffalo are in fact not "Buffalo people", contrary to popular belief. They are Buffalonianistas, or "America's Canadians".
