because they are for chads. They checkmate your opponent's confidence
Who even plays these openings?
Someone mentioned here a few years ago a fascinating fact that Kasparov has never beaten an opponent who played played the Bongcloud against him, true at the time. However I guess miracles can happen...

I didn't see anybody using these openings yet
Hikaru did play the Bongcloud
But that's all what I know

1. King's Gambit Accepted: Tumbleweed Variation
2. Bongcloud
3. Barnes Opening: Hammerschlag Variation
I don't know why do they even have names, these openings...
