A straight-up bro. A bubby is the type of dude who would jump into the cataclysmic depths of hell, fight the lord Cthulu, and return with your father's golden crown just to make sure that you get to hit that piece of ass in apartment 6.
THE country stereotype, in real life. He normally wears a lot of camo, may chew tobacco, speaks in an annoying country accent that uses words like "cruck" (truck), "crick" (creek) and "code" (cold). The naming for this comes from the fact that he calls any immediate family or friends "bubby".
