Teabagging is an art, a very underappreciated one, and the ones who do not appreciate said art are the ones who get annoyed by it. That is why we must keep spreading the art of teabagging until everyone truly appreciates its beauty.
I prefer to hear the crys of little kids, OMG HES TEABAGGING WTFFFF
I've never really teabagged in this sense, I just prefer to crouch dance. Teabagging as you've described it sounds hilarious though.
Sometiems I'll choose Toro and crouch up and down the entire match for the fun of it. It's also why Sackboy is my #2 favorite character - best crouch/super combo. I'll play stock quick match, use my level 3, run near their bubble so the screen zooms in and then crouch up and down repeatedly. Sometimes I'll sing Bohemian Rhaposdy as I dance to add to the excitement.
