What mainstream U.S. might think if they heard some of the phrases that get yelled at us as we're running races:
We hear: "Dig deep!"
They think it refers to getting the last of the bean dip out of the jar.
We hear: "Go balls out!"
They think it means going without underwear.
We hear: "Show some guts!"
They think it's something you'd say to get frat-boys to take their shirts off.
We hear: "Relax!"
They don't see how you can do that and run 5 miles at the same time.
We hear: "Nut up!"
They think it has something to do with how one testicle doesn't hang as low as the other one.
We hear: "Stay on him!"
Let's face it, that sounds kinda gay.
See if you can think of any more.
