I noticed this as well and it kinda reminded me of myself haha. Since about 7th grade I always had a neck twitch that i constantly had to do, even more so when I was in a pressure situation. I played basketball up through high school and my senior year heard some pretty ridiculous things from opposing players and fans so I kinda know how CJ might feel with it. I remember a game were I was at the foul line against a rival of ours and the fans chatning "twitch, twitch, twitch!" or "neeeccck brace" lmao. Honestly i just thought it was all funny and flattering cause not like there was anything I could do about having the twitch haha
