Is a theory of online trolling mentioned in South Park in which an initial troll (Person A) makes offensive or controversial remarks to another individual (Person B) with the intention of provoking a reaction from a third party (Person C). The intention is that person C's gross overreaction and self righteousness to the trolling of person B will elicit further reactions from persons D through F who are not trolls but cannot help themselves from ripping on person B. Thus causing a fission like chain reaction leading to an explosion that brings out the worst in humanity. Initially used by desperate celebrities to further careers. Trevor's Axiom can also be used by politicians and media spokes persons as an alternative for skill, aptitude or talent in generating public support.
"I cant believe that piece of shit would say that about minorities/the troops/gays/disabled people I am gonna give them a piece of my mind"
"Dude chill they are totally trying to use Trevors Axiom to get a reaction from you"
The axiom that states that Asian women from below the 23rd North Parallel are disproportionately hot. The converse is also true; north of the 23rd Parallel shows low average hotness.
Man 1: Man, that Asian woman was hot!
Man 2: Cool, where was she from?
Man 1: Vietnam, I believe.
Man 2: Exactly, it's the 23rd Parallel Axiom at work.
