Police code for Black male.

all units be on the lookout (BOLO) for a Ford Bronco being driven by a number one male down the 405. number two male would be White. number three would be Hispanic. beyond that they would just use the name of the race on the airwaves.

Number Seven 

A type of pencil that nobody EVER uses, but someone will inevitably bring it to a test that specifically requires number two pencils and won't realize their mistake until they're at least halfway through.

My teacher's bringing extra number two pencils for the inevitable kid that brings a number seven pencil.

Number 11

A very bad word emphasized on an episode of "Spongebob Squarepants" where Spongebob learns a nasty word, presumably the word fuck or shit, or bitch. And cause a fuckload of disturbances around the Krusty Krab. The Number 11 is a very naughty word and whoever says it gets snitched on. Number 11 is the word: "Fuck".

Jim: Fuck! I forgot to save!

Michael: OOOO, you said number 11! I'm telling mooommm.

(number here)-timing 

A condition where one person is cheating on somebody with a variable number of people. If it's two people, two-timing, if it's five people, five-timing, and so on. Anime characters have an unfortunate tendency to do this, especially males.

Guy 1: Hey, did you hear? Apparently, Johhny's two-timing on his girlfriend.
Guy 2: Better than that guy in anime. That guy's 16-timing, and that's not including the 2 girls in the past. (number here)-timing
