Another word for a breathalyzer, which is a device used to monitor one's blood alcohol content (BAC). Dubbed 'the Lahey juul' because in the television series "Trailer Park Boys," Jim Lahey (park supervisor) frequently uses a breathalyzer in a similar fashion to a nicotine addict.
A highly concentrated nicotine vaporizer which underage kids use to get a buzz. It is commonly mistaken for a USB stick which makes it easy to take use in class. A rip from this device is usually referred to as a 'wop' and the stick itself is also known as a wop machine. High school age kids often ask to use the bathroom, but instead they are getting nic rpped in the bathroom off of wops.
Student: Hey teacher can I drop a log in the bathroom right quick?
Teacher: Yeah get your shitty smellin ass outta my classroom.
Student gets into bathroom and immediately starts takin mad wops from his USB lookin ass Juul.
That nic stick all your kids are hittin these days causes them all to become addicted therefore they start fiending when they run out of pods so they take the blue pass from their math class and camp out in the bathroom waiting for a humble fellow to come in and supply some rips all while avoiding the security guards that enter randomly.
Joey: “yo Vin lemme hit that juul!”
Vin: “bro this my last pod chill”
Joey: “I’ll literally pay you $5 right now for a rip”
Vin: “holy shit ur such a juul fiend”
Sometimes referred to as a "vape pen", juuls are things high schoolers use to get high. There are a lot of flavors, mango, gummy bear, cotton candy, and your mama's dick. Girls hide it in their bras because there's no one that juuls that is of the legal age. Not sure what guys do, maybe their sock?
