Pousto-Tetarth is that one day of the year, usually a Tetarth (Wednesday in Greek) in which all the gay people in the school who dress emo or like the opposite gender, dress normally and nobody recognises them.

Person 1: Damn, have you seen the dyke chick? She got a whole glow up! She went from wearing basketball shorts and xxL tshirts into being a hottie!

Person 1: Damn I thought Pousto-Tetarth was next week!
