A weekday evening, traditionally Tuesday, in which you party as you would on a typical weekend. Participation in a fraternity or sorority is by no means required to enjoy fratuesday, though the phrase was coined by a Delta Sig and a Theta Chi at University of Oregon. A common accompanying tagline is 'It's the Weekend of the Week!'
