Now I've seen some vapers who actually look like these people, and the hoodie-clad party people are just as insufferable as all of the fedoras and quasi-yuppies and zany wacky ladies who have made a retarded lifestyle out of vaping.
If you have to put fluid in it, it counts as far as I'm concerned.
Either way it's people who make their vices (which I don't care about) into the core of their lifestyle and identity (which is almost always nature's way of telling you you really don't want to get stuck in a conversation with them).
Fluid style cannabis vaping is not very popular. People use pens or dab rigs the vast majority of the time, and it doesn't use fluid, it uses solids. And yes, overly centralizing your life around how you become intoxicated is always a negative thing.
