Abuscure 

To attempt to become important among an obscure setting; seeing a group as inferior to bring attention to oneself

Mark is a very abuscure person, always trying to seem important among our little-known community.

abscure 

when something is obscure and abstract at the same time.

That reference is not only super random, it's completely abscure. Who would know that or even understand it? You're crazy, you know that?
