Any coaches or PE teachers have issues with lazier athletes or students calling your hard working kids a "try hard" as an insult. It's become a popular put down at my school for kids who work hard in PE or athletes who work hard or attend optional weekend workouts. It's not a big deal but I've heard it daily for the last few months and I don't ever remember hearing before. I'm at a middle school with a no cut xc program and many kids are just there cause they get cut from everything else and want to be on a team or the parents want them there for various reasons including free day care.
