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.

Get the Ten Billion Humand Second Century mug.
A rule often employed for those who seem to be over-exuberant or too comfortable in their surroundings. 10 seconds before you start speaking, stop.
Shut up or I'll be forced to implement the ten second rule!

Get the Ten Second Rule mug.
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.

"Noooooo waaaaaay....the OTHER SIDE....HAHAHAHAHAH!"

The amount of time it takes on a blind date or a computer date site date before you realize that the next hour or two is going to be a total waste of time. In other words: you're not attracted.
Dude #1: How was the date last night?
Dude #2: Horrible!
Dude #1: What? She fail the ten second test?
Dude #2: No, I think I did! She hardly talked to me or looked at me the whole time.
