Groovster

Groovsters came about because hipsters are too mainstream. Groovsters make very ambiguous/vague references that only other groovsters would understand. They never actually say any names, places, or descriptions that would allow for a non-groovster to understand the reference. Groovsters don't have a uniform style of clothing because that is too main stream. You can only figure out if someone is a groovster if you already know for a fact that they are one.

Groovsters are so non-mainstream that if normal fish are mainstream, and salmon are hipsters, then groovsters would be that one thing by the stuff.
