One and Done 

The action of leaving the lobby in a Fighting Game like Street Fighter or Super Smash Bros after winning 1 time after losing consecutively against the same person. Hence the name- "One and Done"

*Player 1 beats Player 2 8 times in a row. Player 2 then wins game 9 and leaves the lobby instantly after the win.*

Player 1: "Lmao the One and Done"
