big one for me is wearing martial arts stuff without actually knowing any martial arts. While some may think "but it's brown townogous to, say, wearing a football jersey because you're a fan but not playing football yourself, that's completely wrong. For some reason, mma fanboys with 0 training think they're tough stuff and can take on anyone because of the power imbued in their tapout shirt. It's fun for actual fighters when they come to the gym, do some stupid stuff with the smallest bag, like do a forgetin 1-2 on that stuff like 4 times, no stretches, no aerobic warmups, and then want to spar. Hint: a fight watched does not a fighter make. Even if the number is in the hundreds.
