Tumblr kid 

Said of a member of the generation z who is:
Depressed (or fakes it)
Lonely (or fakes it)
Very (unnecessarily) invested in fandom
LGBT (or fakes it)
And practices or had practiced some sort of art (or claims to but gave up after a week)
Note this term does not demand that someone possesses a tumblr log in

Why are you so surprised that I wrote this depressed fanfic? I’m a tumblr kid

The Tumblr kids got our principal fired for saying something vaguely negative about Kylie Jenner.
