What term do you use for a generic person: bro, buddy, dude, fella, or pal? Jack Grieve, a forensic linguist, analyzed tweets to create heat maps showing the relative frequency of these words. You can view the other maps in the series at Quartz. Where are your bros? They're down in Texas and its neighboring states. If you prefer the company of dudes, then you may wish to move to the Southwest or the Midwest.
