Tetrisgender

Tetrisgender is a term with two possible definitions. The first definition is a subset of gamegender where one feels that their gender is "gradually stacking up" before being removed, similar to how lines are cleared in Tetris.

The second definition is where a person feels as if their gender is connected to the game of Tetris itself, or incorporates Tetris into their gender to better understand/explain it. Like the first definition, it is also a subset of gamegender. It could involve a connection to a certain piece from Tetris, but it does not have to.
