501 Alarm

501 alarm
(adj./noun)
A slang term for someone acting so dangerously chaotic, loud, or obviously unhinged that they’re basically guaranteed to get the authorities called on them. A “501 alarm” person is operating at a level of behavior that’s past “wild,” past “crackhead energy,” and deep into “you’re about to go to jail or get involuntarily hospitalized” territory.

“There was this man on the corner acting so erratic and cracked-out that he turned into a full 501 alarm.”

“What happened?”

“He started throwing rocks at people’s cars as they drove by — caused so much attention that the cops pulled up and scooped his ass instantly.”

8,456,501,250 

A number hypothesized to be the total number of colours in the RGB colour model, if you do the math, it does make sense. The calculations for this hypothesis are: 255 x 255 x 255 = 16,581,375. 16,581,375 x 255 = 4,228,250,625. 4,228,250,625 x 2 = 8,456,501,250.

8,456,501,250 is a number which is hypothesized to be the total amount of colours in the RGB colour model.
