Another big problem with pranks is that there is no set definition of what they are. Pranks are an area that would definitely benefit from a law saying, "These are pranks, and anything else is unqualified nonsense," because as long as it vaguely follows a certain format, anything that I say I'm going to do and then don't really do could be considered a prank. By the standard set in these videos, if I walked up to someone, announced, "I'm going to hit you in the mouth!" and then kicked them in the junk, I could say, "It was a prank! Like, share, and subscribe!" It would hit all of the requirements for being a prank, of which there are two:
1. Someone feels soooooo smart when it's done.
2. Someone else feels sooooo stupid when it's done.
That'll teach people to show concern for their fellow human beings, assholes!
However, it's just such an oddly malicious attempt at screwing someone else over that it becomes impossible to laugh with the person doing the prank. They can put the "humor" tag on it as much as they want and it still won't make a difference, because these prank videos aren't intricately designed traps that unsuspecting people fall into. These are excuses for us to watch something where some idiot might get punched in the end. They're hidden morality tales. You wait for the guy doing the pranks to get his comeuppance for being such an uncomfortable cock ring on the dick of the world. If it was anywhere else but the Internet, it would be the story of someone who messed up and was taught a lesson.
But this IS the Internet, which is built on the backs of confused people trying to come to terms with the idea that they're not good at as many skills as they'd like to be, so they bask in humiliation with a lack of self-awareness that seems almost robotic. It's the kind of climate where a vlogger couple will immediately broadcast their pregnancy announcement and subsequent miscarriage announcement, because, holy shit, look at all of the clicks that we're getting. The cleverness of the prank is never what is applauded. There are barely any successful compilation videos of the pranks going well. But millions have watched them go poorly because we legitimately don't care if the worst thing happens to their stars.
