Ultimateball is Another Made Up Sport

Is “ultimateball” a real new extreme sport? I honestly can’t tell. Is Ultimate Tazer Ball actually real? What about combat juggling? Wife carrying? Extreme ironing and Kronum? What even makes a real sport? Certainly not being in a YouTube video. These all seem so stupid and dreamed up that I can imagine any of those things are “real.” Having said that, why would anyone go through the trouble of making them up?
