Certain people of the indie variety who may be considered Hipster in most circles, but never actually went full hipster. A proto hipster has the ability to acknowledge cultural norms, and chooses to exceed them to an extent.
A proto hipster must meet all of these conditions to be considered: does not wear douchebag v-necks on a daily basis or often, does not have a moustache or a full beard, does not wear fake glasses, does not wear buddy holly glasses regardless of weather they are real or fake, does not have visible tattoos, does not have dyed hair, does not wear beanies when it is not cold, does not drink PBR or any other "indie" beer, is not vegetarian, vegan, or on a gluten-free diet.
A proto hipster is generally one who wears funky clothes that does not excessively succeed cultural norms, and listens to obscure music, and watches old or weird movies
Naw dude, I'm a proto hipster cause I never went full hipster.
People who think they're ahead of the trend curve but really are just full of themselves and annoying.
"look at that proto hipster, he thinks he's the first one to wear skinny jeans!"
