Hipster Leech 

An individual who associates with hipsters and trendy people for personal gain on social networking websites, such as tumblr. This involves attempting to dress like a hipster and taking way too many photos with their hipster friends, to appear cool to others online.

Did you see all of Ellen's photos on tumblr last night? She's such a fucking hipster leech.
