The joys of slang phrases in middle school :)

I've been teaching a volleyball unit to my girls in PE and to warm up and get them excited about the games, we've been playing "no rules, no boundaries" for a few minutes before getting started, which is exactly what it sounds like, and using about 10 volleyballs. They have really been getting into it. At the beginning of class today, one of my precious students shouts across the gym to me, "MRS. LANCE! Are we FREE BALLING again today?" I thought it was hilarious, but of course, I pretended like nothing happend. But later, some of my other students told her what else it could mean, and she came to me to apologize. As sweet as that was, though, it still cracks me up!!
