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. For example, a very feminine boy would show up at Pousto-Tetarth wearing the most Chad outfit out there.
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 2: You're such a dumbass. It's Pousto-Tetarth you idiot. Ofcourse she's going to be dressed up like that. Look around you, even the fags are wearing off-courts instead of docs.
Person 1: Damn I thought Pousto-Tetarth was next week!
