My stupid moment:
Was playing couple of rounds on Ghost Mode until my girlfriend and her friend were ready. Soon as I had to go, I quickly finished the match, tapped left to set it on "exit" and left.
When I came back, I saw that my controller was vibrating.
*My God* I thought to myself.
I turn my game on in horror to find my character being KOed by the cpu. He had KOed about 56 times until I realized either I accidentally tapped it back right for more matches... or never tapped left at all.
Ruined my offline records - not that it matters much but felt salty at my own stupidity.
What are your stupid moments? Let us bathe in our self embarrassment.
