Let me repeat myself about repetition

I was at the salle this Saturday and the class were merrily carrying out some standard drills. I noticed that some of the older members of the class had finished and were talking and wandered over to find out what was going on. I have to confess that I hadn't slept well the night before so was a bit grumpy and my query was probably a tad sarcastic when I asked if they had perfected the technique. One of the group replied that they'd done it loads of times before so didn't need to keep repeating it. Can you guess what I said.....?
