One of three Diocensan high schools on Long Island. Just a block from the Great South Bay, right on Montauk Hwy, in West Islip. St. John's or SJB is a great school with dedicated teachers and kids who love to have a good time. People are nice and its hard to fall through the cracks at this school.

Like most LI school SJB is big on athletics and some favortism can be seen, but not much. Teams like the boys and girls cross country team, boys and girls varsity basketball, badmitton, gymnastics, and boys soccer tend to compete very well within the catholic league and even States. These teams bring pride to the school and student always come out to a home bball or soccer game. the "red sea" and "whitout" are two popular themes to home games and it's truly a sight to behold.

There is also favortism for the exceptional student and you can always tell the AP/Honors kid from the average/"regents" kid. The school is a lot stricter than some other well known Catholic schools-rules which remain from the "drug age", while the student population has gotten better, the rules have not decreased a bit.

The mascot is the Cougar
St john's kids are often seen as stuck up or "elitist" because of the high tuition but the truth is most come from middle to upper-middle class families who sacrifice to send thier kids to SJB.

SJB's biggest rival in most sports is St. Anthony's Friars

Nerdy, short, mean, average looking bullies who annoyingly obsess over girls from other schools, especially Kinkaid. They have bad BS and no game. They're bad at sports too.
Robs Girl 1: It’s so annoying how the river oaks baptist boys ignore us.
Robs girl 2: Ik!!! All they do is hook up with Ava, Anna Cate, Brisa.

A Catholic High School located on Long Island. It has very strict rules, stuck up kids, horrible flight attendant-esque uniforms, REALLY stuck up kids, and a knack for spreading rumors. Everyone hates on one another and will do anything to save themselves from getting socially wrecked. Once you enter there, you change. Everyone is shallow and no one makes it out innocently. No one learns anything because everyone's too busy with gossip. The minds of the kids are controlled by the "popular" kids, so no one thinks for themselves. Quite sad, actually. Also, if you dye your hair, you can get expelled or some shit like that. No one is accepted unless you like to give head to stupid boys who are going to dump you anyway. In short, if you go there, you're screwed.

Also see: Hitler Youth, mean girls, Chinese water torture, Concentration camp
Girl One: i can't believe he dumped me right after school started! he was that ashamed of me.
Girl two: well, does he go to St. John the Baptist Diocesan High School?
Girl one: yeah...
girl two: hmph. figures.

Teacher: and so, Hitler formed concentration camps because he was highly discriminatory against all non-germans and jews.
Smartass student: so he went to St. John the Baptist Diocesan High School, right?!
