816

Pronounced "eight-sixteen" and alternatively written as 8:16, this number is the sound of one hand clapping, and if a tree falls in the forest with no one there to hear it, 816 reverberates through the lonely woods. It is Chuck Norris' favourite number. This is a number that laughs in your face. Just look at it and you will understand.

'Capital 816 period.'
'Man, that was so 8:16'
'I want to 8:16 you so bad'

815

Bowel Movement (v), dookie, dump, the act of pooping.

Not unlike the evolved meaning of 420; this began, locally, when a manager (at an undisclosed business) always performed his morning ritual at exactly 8:15 in the morning. Everyone in the company; and, by extension, ex-employees; began describing their potty time as "815" (pronounced Eight Fifteen).

Dude, my gut is killing me. Of course, I'm an hour late for my 815!
