IT'S A COMBINATION OF MARTIAL ARTS AND GYMNASTICS. CHARLIE: PUT TOGETHER IN SPECIFIC COMBOS, THAT EXPRESSES YOURSELF. PAUL: YOU'LL SEE FLIPS AND KICKS JUST DONE IN WEIRD, UNORTHODOX WAYS. STEFFANI: PAUL TONG ARRANGED THIS GATHERING OF TRICKERS FROM ACROSS THE COUNTRY. PAUL: YEAH, IT'S NOT A COMMON THING. SO, IT'S A SPECIAL THING, WHEN YOU FIND SOMEONE ELSE TRICKING. STEFFANI: THEY'RE CAMPING OUT INSIDE MERLE HAY MALL THIS WEEKEND, PRACTICING THEIR TRICKS. >> YEAH, PAUL. PAUL: I WAS IN A CHINESE MARTIAL ARTS ACADEMY AND THEY HAD LIKE ACROBATIC STUFF, BUT THEY DIDN'T TEACH THAT. THEY ONLY TAUGHT ME FIGHTING FORMS. BUT I REALLY WANT TO LEARN THE COOL STUFF. I WANT TO BE A NINJA. STEFFANI: IN TRUE MILLENIAL FASHION, THE INTERNET GOT MOST OF THEM STARTED. PAUL: YOUTUBE, THAT'S WHAT EVERY TRICKER WILL TELL YOU. STEFFANI: BUT THEY SAY IT'S NOT THE KICKS OR FLIPS THAT MAKE THIS FUN. CHARLIE: TRICKING PULLS PEOPLE TOGETHER WITH THAT COMMUNITY, RATHER THAN JUST DOING THE MOVEMENTS. STEFFANI: NOT TO MENTION, IT'S A PRETTY GOOD WORKOUT.
