What is an American flag shirt? The Merriam-Webster Dictionary defines the word as: n. An article of clothing reserved solely for the red blooded, commie fighting, Waffle House eatin’, no BS sons of bitches who have fight in their heart, and heart in their balls, or lady balls (what’s up 19th amendment). While that might seem like a long winded and strange definition for a highly reputable dictionary, if you don’t believe then look it up yourself. Also buy some USA t-shirts and tank tops while you’re here, because that’s probably what led you to read this absurd paragraph to begin with.
