A person who will boast or brag about seeing a video on YouTube before it became popular and got a lot of views.
Regular person: "Dude, I saw that Evolution of Dance video on YouTube last night; that video has almost 170 million views! That guy is pretty good!"
YouTube Hipster: "Yeah, I remember watching that video before anyone was talking about it. It only had, like, 5 thousand views at time..."
Regular person: "I hate you."
Adjective: A person who finds it completely necessary to complain about how YouTube has gone corporate. YouTube Hipsters can be observed in the comment section of any Vevo video usually expressing an opinion with no backing, begging for thumbs up, as they feel the amount of thumbs up directly correlates to the size of his/her penis.
Youtube Hipster: Wow, I remember when users uploaded songs, not Vevo! Thumbs Up!!!!
Youtuber: STFU n00b
Youtube Hipster: Wow, look at all these ads, I remember when youtube was about fun, not money! Thumbs up so everyone can see!
Youtuber: download Ad Block and stop complaining. God I hate Youtube Hipsters
