A fluke is something you do by accident that’s really incredible but you can’t replicate it/ do it again for nothing or anyone else.
When You kick the basket ball off the mountain top and it went through a basketball rim net . It was nothing but a fluke. Can you believe someone edit rim to room while I just got done reading it ? Can you believe it. Now re read everything once you done typing. That’s call proof reading.
Have a lower percentage and then go all the way to the end in a game called Geometry Dash. Also can be used to describe going from like 20% to 60% in a level. It has to be a significant jump, so something like 80 to 100 would not be considered a fluke, at least in shorter levels.
