Pseudoartsy

Pseudo = "wannabe" , trying to look like
Artsy = connected to art

So it is anything, what's trying to look like art.

If a girl posts a photo of her "organized" study space with a burning candle or a small cactus, it's usually just pseudoartsy, because let's face it, it will never be a valued piece of art, because there are plenty of similar photos on this site.

Or a photo of alcohol and burned cigarettes might bear a very deep meaning according to the photographer, but in reality it's just another photo on of alcohol and cigarettes on Tumblr.
