True Blue Football [troo bloo foot-bawl] noun: The two hours once a year that BYU seems to lose every last scrap of sanity. Basically, Helamen fields are flooded with two feet of frothy, bright blue foam, including two giant slip-n-slides down the hill. There is an area to dance and swim in, complete with tug-of-war and strangers letting you borrow their giant, inflatable sharks to slide around on.
