Arm Rest Showdown

The unspoken battle for arm rest position/supremacy between you and the over-sized individual who sits next to you on the plane.

Ugh...I lost my arm rest showdown with the slob next to me and had to spend the whole 6 hour flight straight-jacketed in my seat.

arm rest anxiety

The awkward moment when you're sat next to a stranger in the cinema, and there is a mental dispute as to who gets to put their arm on the rest...

You: "Dude my arms are really aching..."
friend: "why dont you rest them on the arm rest then?"
you: "nah, got arm rest anxiety"
