braintellectual 

A portmanteau of the words brain and intellectual that describes individuals whose intellectual capabilities are so great that they understand this word and probably more complex subject matter too.

The opposite of brainlet.

It is very commonly used in a sarcastic manner.
It can be used as an adjective or a noun.
