Y'all, quit talking about the Vape Pen! Also, to the person who said Juul is slang for Vape, that's inaccurate. Juul is a brand name. However, it is used as slang, much like Coke is a diminutive of the soda made by an Atlanta Company of the same name, but is also used as slang for all sodas. Especially by Southerners, aka Southern Americans (not South Americans). Or how AirPods is the Apple Inc. brand of wireless earbuds, but some people call all wireless earbuds AirPods as a slang term. But Juul, Coke & AirPods themselves are brands, not slangs. They're merely *used* as such.
