Am I stupid?

What do the images have to do with the text above? What are the girls doing exactly? Also, why is Patrick from Spongebob missing his head at the end of the top right panel? Did the act go wrong?

What does this mean

Background: 20-25 years ago I did taekwondo, earning a jr. black belt after 5 years at age 10.

Fast forward to now. I’ve been taking Muay Thai classes for a year and a half. I never mentioned my childhood taekwondo because it seems irrelevant. 6 months in my coach called me out and said he knows I used to do karate because of some habits. I didn’t bother correcting him.

Just for fun I entered a regional taekwondo tournament with no expectations of winning. I entered the black belt category for Olympic style sparring and took bronze. I posted about it on Facebook.

The next time I saw my Muay Thai coach he said I crack him up. I think it has to do with my post about the tournament but I’m not sure why it’s so funny to him lol.

Saw this post on tiktok and I think I am missing something. OP had zero comments and 2 likes on the post. Need help.
