If you’re a male in Texas and have one or more BFFs, then chances are that you refer to each of them as “bro”. If you and your BFFs hang out in the deep south, then you’re more likely to call them “fella”. Fans of the Big Lebowski will be glad to hear the “dude” lives on — but mostly only in California, Southwestern US and around the Great Lakes.

See more maps of bros, fellas, dudes, and pals at Frank Jacobs blog here.
