Pretty self-explanatory - someone who thinks they're a hipster.
This type of person is in abundance on Twitter, usually with the screen name 'Sheldon Cooper'. They also have a habit of ending tweets with 'though', despite the actual tweet having no relation to anything. They also use other annoying buzzwords on Twitter. In addition to this, they think that liking The Big Bang Theory and bacon makes them look really edgy and random, and they all seem to think they're socially awkward despite tweeing their life stories to thousands of followers.
Commonly confused with real hipsters. However, whilst real hipsters stay true to the definition and listen to obscure, unheard of musical acts, Hipster Wannabes like currently popular acts despite them thinking that they're alternative for doing so, such as OFWGKTA, You Me At Six, Two Door Cinema Club, Arctic Monkeys and Foster The People.
They are an evolution of the Scene Kid from the mid-2000s, only more obnoxious and pretentious, and even less self-aware.
Real Hipster: "I think I'm gonna listen to some Ariel Pink's Haunted Graffiti and then head out to drink some Hungarian lager whilst discussing the latest Sufjan Stevens record"
Hipster Wannabe: "Socially awkward but happy because bacon, The Big Bang Theory and You Me At Six though ok"
A person who thinks they are hipster, but doesn't actually understand the true meaning of the word.
These people tend to wear colorful skinny jeans, Converse, Vans, T-shirts from Hot Topic and Delia's, wear Jac Vanek bracelets, straighten their hair, listen to punk goes pop bands such as NeverShoutNever, All Time Low, Boys Like Girls, Cute is What We Aim For, The Academy Is..., Cobra Starship, etc. and think that just because there are tons of bands within that same punk pop genre, certain bands are more obscure than others, and these obscure bands are "indie".
*They may also believe that they are so hipster because they hate Twilight, but they like Harry Potter.
"Yo, look at my 3D glasses with popped out lenses and my Stereo Skyline T-shirt and my Harry Potter posters! I'm such a hipster"
"No. You are just a hipster wannabe.''
