I saw something like this recently. My husband and I go to the gym together in the evenings. I was standing at the cable machine and it was my first set of triceps pushdowns. I finish my set, and some obeast comes up to me and asks if he can work in with me. My husband was a few steps away from me, and there were other cable machines open, so I didn't know why this guy was asking to work in with me. Maybe he was trying to hit on me? Who knows. I looked at my husband and he came over towards me, so I told the obeast there was 2 of us and we had 2-and-a-half sets left each, but he could work in if he still wanted. So my husband does his set, and the obeast is trying to act all tough and does the same weight as him. He does about 6 reps and slams the plates down, making this dramatic grunting noise as he does it. So I reset the machine to my weight, do my set, and my husband does his set at his weight. The obeast does the same fucking thing as before. I thought he was going to break the damn machine because he was being so stupid and slamming the plates around. Thank god he waddled off after his second set.
