Thats when you put on the mask... and play it off soooo well!
Or when you screw up hard and it some how works out. And you stand there hoping your teammates didn't realize that wasn't the plan.
You just explained pretty much every good play I have ever made. I got a pentakill with Shyvana once, but for the first 3 kills there was so much chaos I was basically just mashing buttons and hoping I was winning. But when I come up with detailed plans on how to succeed, I always just end up tower diving (don't ask why. I have no idea).
