a lumberjack is a person who wears all plaid, every single day of their life. lumberjacks can be either antisocial or popular, and they are usually male. however, rare female lumberjacks have been spotted on occasion.
this strange group of people is a very rare subset of what is now called a hipster... the lumberjack makes being a hipster look nerdier than ever through their overuse of the plaid pattern and other hipster elements.
is you happen to meet a lumberjack, don't scare him or her off! you may never see one again!
it looks just like all your other plaid shirts... how am i supposed to tell which one it is? you're such a lumberjack!
