Thinkest 

The mastermind in the class or work or in-game.
But with a twist. He/She is the most creative person but too lazy to create it.

This job is made for Thinkest.
I stole Thinkest's idea but it was too complicated to understand.
I'm so Thinkest. I have so many ideas but am too lazy to do it.

The second guy: Thinketh is not a word?
The first guy: I thinketh you haven'teth readeth shakespeare
