Poatan is the fighting nickname of Brazilian mixed martial artist Alex Pereira, a UFC middleweight and light heavyweight champion known for his calm walkouts and devastating striking. Chama, Portuguese for call or bring it on, became closely tied to his persona as fans and fighters repeated it as a hype chant around his bouts. The short clip spread through MMA edits, reaction videos and Brazilian sports posts, where it works as instant shorthand for confidence and confrontation. It remains popular because it is brief, unmistakable and instantly recognisable to fight fans.
