Catch wrestling is a type of fighting that involves trying to hold your opponent down on the ground so they can't move. You try to put them in a "pin," or hold, that is hard for them to escape from.
In catch wrestling, you also try to make your opponent give up by putting pressure on different body parts to make them hurt. This is called a submission hold, and it's like saying "uncle" because you can't take the pain anymore.
Catch wrestling is similar to other types of fighting, like wrestling and Brazilian Jiu-Jitsu, but it has its own special moves and techniques. People who do catch wrestling are really good at thinking and moving quickly to take advantage of their opponent's weaknesses.
Overall, catch wrestling is all about trying to control your opponent and make them give up by hurting them, but it takes a lot of skill and practice to get good at it.
