When you're too good in League of Legends that you win anyways

I was just in the top lane, and Nasus and me (Kennen) were at a standstill, farming from little minions, and then when we talked via /all, we agreed to 1v1 top lane at lvl 15. We both never got to lvl 15, and I remained top to get levels, then when the scores were just too bad against them, they agreed to a surrender. I never got that 1v1 though...
