Double boops have been a thing for a long time, usually done by slowing down and speeding up again, recently someone figured out it was easier to double or more boop by spinning the camera 180 back and forth (or 360) really fast. This has become the dominant way to double+ boop now I believe. It's considered easier.
In this replay R773QT you can see a hammon on red team using some kind of exploit to get enough boops to instantly kill a player over and over
My theory is he's using something automated to spin his camera insanely quickly as he moves forward to hit the target for enough boops to one shot them. You can see this happen in his very first kill of the game as well as continously after that.
This is going to spread quickly if not addressed.
