Eristic 

A kind of contentious reasoning that seeks to appear victorious in disputation, without regard for truth. It is distinguished from sophistic because it is not concerned with appearing wise, only with seeming victorious in disputation.

The following are some well-known eristic arguments taken from Aristotle's On Sophistical Refutations.

Eristic argument 1. There is sight of what is seen. The pillar is seen. Therefore, the pillar has sight.

Eristic argument 2. Whatever you profess-to-be, that you profess-to-be. You profess a stone to-be. Therefore, you profess-to-be a stone.

Elastics Gymnastics 

Any series of physical exercises designed to squeeze one’s arse into a pair of pantyhose, snug jeans, and such.

I almost collapsed from exhaustion and dehydration after a grueling session of elastics gymnastics with a pair of tights.
