A regional highschool in Somerset Country New Jersey that pretty much lives in the shadow of Ridge High School (the wealthy, not trashy part of Somerset). Many of the students try their best to hookup with students from Ridge in order to make themselves feel slightly less worthless. They play dirty in sports to cover the fact that they suck at them, and many of them go to the mall every friday night to convince themselves of having an exciting social life, when really they're just hitting on trashy strangers (usually from bridgewater or bernardsvlle).
Dude: "Hey bro, did you see that swamp crawling with vermon we just drove by?"
Bro: "No dude, that was just Watchung Hills Regional High School."
