ELI5: Can someone explain Shia LeBouf's speech to me (as in why/how)?

How did it even come about? Was he being totally serious? Is he just cracked out? I'm baffled by it. Was it for something in particular? I suppose I just need background information on it.

The "do it" one?

IIRC that was done for a students short film. Not sure if it's entirely improv or if they outlined what he had to say. It was shot on green screen so they could edit him in. They wound up posting the raw footage and he wound up cut into everything.
