Definition- Fat Friday, also commonly referred to as 'Greeday', is the last Friday of the month where one can simply binge on any food one desires. Fat Friday is set aside for those who maintain healthy bodyweight on normal days and not for the continuously gluttonous or obese.
Comrad: Friendo, why you be eating so much today?
Winston: Cousin its Fat Friday you know. Gotta let loose.
