Sinpla 

People who constantly use the word- "Simp", even when it is not applicable.

Such people are mindless sheep-like individuals who just say or do stuff because others do it. They are against basic human decency to a certain sex and dislike people who address it.
Some of them, unironically tend to be simps, themselves, who are merely jealous.
They can below 13 or above and can even reach to boomers, who use it as an ad Hominem tool.
They rarely use "simp" for it's correct meaning.

Rogen: I have save Malorie, she is being raped
Laril: You are such a simp. Are you saving a girl?
Rogen: Have you gone loose on the head? She is my sister
Laril: You must be an incestous simp
Rogen: Stop that, you are behaving like a 12 year old sinpla.

Sinclair Secondary School 

High school in Whitby, Ontario that is run by teachers who are unbelievably pretentious and think their school is the best. A high school that has a very high rate of teachers who's kids also attend the school and win every award possible.

Hey did John win the athlete of the year at "Sinclair Secondary School" last year?
Well yeah, his dad is the head of the gym department so its inevitable that he'll win.

A horny ass motherfucker who is simping for 3 or more girls at the same time. The girls think they are queens but in reality, he is playing all of them. Downloads Tinder to scout for new candidates for his roster.
