Logical Fallacies in league of legends

Was recently thinking of my interactions with the community and all the logical fallacies they employ to feel like they have "won" the interaction. If you have any to add, lemme hear em. Not sure what to call it but Basically the go to fallacy I see the most goes something like: Person A: Wow, (Kha) is busted right now. Person B: PFFT YOU'RE (insert literally any champion in the game you happen to be playing). Thats it. Thats the rebuff. The entire "argument" so to speak. Nothing else need be said and at that point they think they are the wittiest person in the world. Anyone have a name for that?
