flailtard

A tweaker that is unable to stop flailing. Usually they are unable to stop moving their limbs and can be seen searching everywhere for nothing in particular.

Oh my god, it's 3:30 AM and Jill is being a flailtard.

Hipster

A hipster is someone that always has something negative to say about the things you like, but will never tell you what they like.

A hipster never takes any risks, so as to avoid any potentially embarrassing or awkward moments. And yet they're the first ones to critique your actions, and tell you why you're wrong, what you should have done, followed by a story about how they did it so much better blah blah..

You never have anything positive to say about the movies I watch. Quit being a fucking hipster.
