Your classic post 2001 male artist country song that includes some, if not all of the following: Friday night, a girl in tight jeans, ice cold beer, a pick-up truck, a sunny day followed by some moonlight, a watering hole, fishing, 4-wheelin', dirt roads, ball cap, working all week and possibly church.

The torchbearers of bro country these days include: Jason Aldean, Luke Bryan, Blake Shelton, Billy Currington, Florida Georgia Line, Joe Nichols & Jake Owen.

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.
