a Nintendo Minute
A Nintendo Minute is when time is like a sadistic teacher giving you a pop quiz with no warning.
"Time was like my teacher giving me a pop quiz right before lunch. I failed.", @MarioMan2000
"I was in the middle of a level and time came out of nowhere and yelled, 'Surprise!", @SonicSpeedy
"Time is the worst teacher ever. I failed my life.", @NinjaGaidenNoob
