This isn’t the golf course—you’re not in the ring to do the “gentlemanly” thing. You’re here to win, and taunting is part of the game.
One of the most useful strategies is to know your quickest taunts (~2 seconds) and press that taunt immediately after you score a knockdown or Irish whip. Check out your Superstar or Diva’s taunt times on their profile page to find out which directions to press. If you can taunt and still hit them while they are down (or pick them up to keep the advantage) you can max out the momentum meter quickly.
