A magical spell to instantly remove someone from anything they're doing on their computer, instantly making them feel ashamed and Low IQ. You can cause the spread of Alt+F4 trolls and remove all fun from computers and be the top of all computers, nobody else will be able to use them because they are addicted to Alt+F4, and despite countless times they've been betrayed, and they despise it, they can't help doing Alt+F4 because they are glued to the spell that you have created; a small, funny, troll-worthy, destructive, key combination. You have created this monstrosity of a spell, nobody can fix it, not even you. It's over. Your small mistake has affected a whole generation, and much more from that point. Computers are now fully unusable, because of you and your small spell. It's over. IT'S OVER.
