A unit describing how improbable a thing is, defined by Matt Parker. If a ten billion humans would do something every second, none stop for a century, it will happen 3.15×10^19. Based on that, you can be sure that if the probability of something is worse than a Ten Billion Humand Second Century, its not gonna happen.
"If i keep trying, i can eventually get a hollow knight speed run where every enemy give me essence, right?"
"Thats can't happen is Ten Billion Humand Second Century, thats not gonna happen. Unless you gonna use a mod to get some dream luck..."

Dude #2: ...aaaand that's ANOTHER ten SECONDS that you'll never get back from COMPLAINING about it!

The delay that comes from being way too high. The reason you laugh after everyone else has gotten a joke, fail to grab a railing in time, raise your hands after you've been punched and redirect your aim only after you've peed on the floor.

(crowd laughs)
(you look blankly at the teller)
