Meaning you "own" someone completely, to the point of extreme embarrasment. This phrase got some attention due to the "Genocide Path" of the popular gameUndertale, where, if you try to spare the last person in your way to the game's end, get trolled and see this phrase as a message afterwards.
Ex. 1: “Ay bro, I got COVID-19.” Says guy 1. “Get Dunked On!” Said guy 2. Ex. 2: “Any last words to say to your grandma before I pull the plug?” Said a doctor. “Get dunked on!” Said Mike Hunt.
