A red brick building where old, sad, and lonely teachers with no life go to yell at kids because they have nothing else to do with their lives. It is also a common belief that most adults in Masco are working for the devil.
For example: Kid: “go to Masco!” Mom: “watch your mouth!”

the act of a male shaving the crack and hole of his hind quarters, despite the anticipated itching that will result when the stubble starts growing out.
Time was running short before the love parade, and my only option was to masco myself.

The school of Tik Tok Thots that do way too much renegade. Your Spanish teacher will even make you do renegade in front of the whole class. Geometry Lab is like entering the ghetto. The teacher will scream at you for not having a ruler. The only good thing about this hell hole is that there's a "vine day" where you can drop croissants and scream.
Masco Student 1: Ay dude you see that girl doing renegade over there?
Masco Tik Tok Thot: *does renegade 500 mph*
Masco Student 2: Yeah shes a thot.

Masco Student 1: Yo you ready for Geo Lab?
Masco Student 2: Nah man, I don't have my ruler.

Any girl that goes to Masconomet and wears Uggs, a Northface, or a very low cut shirt every day. They tend to wear approximately 2 tons of makeup daily, straighten their hair, and frequent local tanning salons as well as Victorias Secret. They also live a large portion of their life on Facebook. it is very hard to set apart one Masco Biddie from another, because they all look exactly the same. As well as being extremely fake, they are also very shallow and unbearably annoying. It is nearly impossible to hang out with a Masco Biddie for over a half hour unless you are going to score with one. Please note that it is very easy to get with a masco Biddie.
Jeff: hey Rob, did you get any with Christina at the liberty tree mall last night?

Rob: yeah man, and after she left i got with her friend Aayla too.

Jeff: sweet dude Masco Biddies. dont forget to sanitize.

When you see a girl from Masconomet High School the first time, she looks alright or maybe even kinda hot. The second time you see her your wondering how drunk you mustve been but then realize you were not drunk, it was just a masco illusion.
Catie and Danielle looked good when I saw them last week but at last night's party I realized those witches were just a masco illusion.
