A flannel, plaid, long sleeve, button down shirt of any combination of black, red, blue, brown, dark green, and dark orange.
Often traditionally worn by lumberjacks, but more recently worn by scene
kids, and indie
kids, especially in the San Francisco Bay Area.
Origins of the word can be traced back to Stephen Fong, Jake Bishop-Moser, and Raisa Monroe-Yavneh, who popularized the term throughout their schools.
