brain-wanking

Act of spending one's time with very complicated theoretical problems which, when solved, do not serve for anything useful or practical.

J: Did you understand the sense of the problem in theoretical quantum mechanics which we solved in our course today?
P: It was just some brain-wanking. It does not have any practical meaning.

Walking the Brain

To pull your ballsack out of your fly and then zip to a suitable point as to which the sack becomes taut; the balls assuming the shape of the two sides of the brain whilst veins serve to add to the realism of the shape.

The ultimate purpose of such a maneuver being to offend when engaging in light conversation with others, subsequently enjoying the outrage when they discover the brain, whilst throughout experiencing the gentle caress of a light breeze on the sack.

Essentially a ball walk but requiring more art to pull off effectively and comfortably yet yielding a much more comical and appropriate name.

Jonny enjoyed walking the brain on a spring day, he was surprised just how long it took some people to notice his nuts were out during his strolls.

brainwanking

Any intellectual/academic discussion meant more to show off the intelligence of the speaker than to prove a point or educate anyone listening.

Freudian literary criticism is pretty useless, to be honest; eventually they stop talking about literature entirely, in favor of pointless brainwanking.
