I'm thinking of pointing and laughing in the locker room at the gym
I don't think that's nice of you. I think you should stop doing that.
It will have the desired effect. This is my plan. I need to do anything possible to achieve my goals.
It's not the place or time to ridicule people or make fun of people in the gym. What would you feel if someone else there would start pointing you and make fun of you and laugh hysterically at you? Try to joke around with your friends outside the gym instead, but make sure that you're not hurting anyone's feelings.
I'm just joking around.
Pointing and laughing at someone is not joking around. The gym locker room is not the place for your antics.
