It works, because it sways the fans. It can also throw your opponent off if they're sensitive. You just have to pick your spots, it's a dangerous move to do it all throughout your opponent's round. It's even more dangerous to do it against a freestyler. When Bigg K's opponent gets a cheer for a corny punchline, and he does that leg kick, it's funny because I feel him. But when he's being sour all throughout the round, it looks lame. When Brizz was doing that "That's a reach" movement in some of his earlier battles, it was funny.
Remember the faces Math was making when Rex said some tough guy shyt during their first battle? It gave that feeling like Rex was talking out his azz.
Charlie Clips escaped a bodybag by doing everything he could to kill B-Magic's momentum.
Remember Conceited vs Jesse James? Remember the way Con was pacing around during Jesse James round like "Is this dude serious?" "Are you done yet?" You don't remember anything Jesse James said, you just associate his name with being corny and trash. A gif of Con's facial expressions is still being widely used on Twitter today.

Conceited was one of the few who pulled this off for a whole round.
He bodied Jesse James while Jesse James was rapping... then he rapped and bodied him again.
Serius tried to pull that off when he battled Math, but he took it too far with the chicks twerking on stage and whatnot. But we would remember that "Whooo" a little differently if Math didn't hit him...
