boolean by jjcp May 14, 2015
A person whom often sees the world, or who's opinions are in an absolute way in which there can be no in-between.

Boolean logic, created by George Boole, has one of two possible values (usually denoted true and false)

boolean algebra 

The only subject in which 1+1 = 1 and you should be convinced.
EX.1

Person1: Jack got F in last exam. The professor says he added 1+ 1 =2

Person2: WHAT A FOOL.

EX.2
Person 1: 1+1 = 1 hhhhhh

Person 2: That's Boolean algebra -,-

Boolean operator 

A Boolean Operator is a conjunction (AND, OR, NOT or AND NOT) used by computer nerds to focus search results and boost their relevance by more effectively specifying the relationships between each search term.

X AND Y ("both" X*Y) will only return results containing both variables
X OR Y ("either" X+Y) gives results containing either one or both variables
X NOT Y ("without" X-Y )can only show results with X that do not have Y
Boolean Operators can massively help you scope your favorite porno shizz, as long as Boolean Logic is supported by the site search on your preferred digital smutpublisher.

EXAMPLE:

For an optimized selection of non-asian schoolgirl porn, the following equation might be an effective use of operators:

(schoolgirl OR school uniform OR student OR teacher) NOT japanese NOT asian

Since porn search engines are more semantically-oriented than Google's RankBrain, searching "schoolgirl" on Redtube might not return videos titled or tagged as "school girl" , "student and teacher fucking" , or "after class BBC bangathon soaks innocent bitch's uniform in semen."

Simply searching "white girl school uniform" might produce a few desired results, but will include many undesired results (people with "white" in their name, non-white girls wearing white school uniforms, etc).

"PAWG schoolgirl" is a decent search that does not rely upon Boolean Operators, but perhaps I like black chicks banging professors for better grades every once and a while...so "PAWG schoolgirl" is not gonna give me much in the way of black chicks. This would be an excellent time to use OR :)

Nigel couldn't find the lyrics for his favorite song, so he called upon the local Booleanographer. Needless to say, the result was good.
