I love gaslighting toxic smurfs
Nothings more annoying than someone who feels the need to shit on lower ranked players and has the nerve to call other people bad while doing it. My favorite thing to do when this happens is to crush their ego. Call all of their shots mid, tell them I've seen better in plat games, call them hardstuck x rank, that no one believes they're smurfing, just having a lucky game. Super funny to watch them beg for a 1v1 and then rage add you after the game.
