When someone in the MOBA game "League Of Legends" plays the champion Master Yi, when this player gets fed in the early game they believe that they can 1v5 the enemy team and proceeds to attempt to. The Master Yi player will most likely fail and blame Crowd Control (CC) and attemp to 1v5 7 more times, thus throwing the game.
Brandon: "Dude yesterday I was playing League of Legends and their Master Yi got so fed and started to carry!"
Jerry: "Did he get Master Yi Syndrome?"
Brandon: "Yeah he ended up throwing the game and letting us win!"
