Soundgarden’s badmotorfinger t-shirt was worn by a Kardashian on insta so top shop will stock it suddenly and 17 year old airhead posers will buy it.

a poser can be someone who tries to fit in faking an interest in something, usually a specific fandom or trend.
poser: Man, JoJo's Bizzarre Adventures is a great and fun anime, don't you think so?
guy: Oh bro, totally! Did you watch Battle Tendency yet?
poser: Pfft, yeah, I watched it all last night
guy: Then let's party, dude! I brought tequila~
poser: *is confused* You know I don't drink, right-?
guy: ...You're a poser, aren't you.

Someone who thinks they're making a major statement or changing the world every time they do something an asshole would do, like it's their first time being that way and they have to do/outdo more to prove they are an asshole to other assholes than everybody else.
The poser thought everything he/she said that an asshole would say needed to end up as a quote online somewhere, otherwise people would remember what he/she was like growing up.

Someone who is only slightly into a hobby simply so they can act as though they’re an expert in it and have an excuse once they are called a poser
