tetriscape 

A combination of the words tetris and landscape. It describes the arrangement of tetris pieces during any game, and more specifically, the topmost blocks. The line of top blocks will inevitably make an uneven terrain, or even a city skyline appearance.

Player1: Whoa, my tetriscape looks like NYC.
Player2: How random!

tetriscide 

The act of giving up and purposely losing at tetris. Generally committed when one feels as if they are absolutely screwed and don't have the patience or skill to try to fix the problem, instead they stack up a whole bunch of pieces in the middle and lose.

Person A-Hey, sweet gameboy.
Person B-Yeah, tetris is the shit.
Person A-I suck at tetris. I always get screwed and commit tetriscide.
