Get the Fucked up big time mug.
An expression that describes something big. A big event, a big shot, a strong emotion, whatever.

It comes from the basketball player Reggie Miller, who is known for making clutch shots at the end of a game.
He had used the expression big time in a Wheaties commercial.
Example: That was a Reggie Miller big-time shot.

Do you like Wheaties? Oh yeah, Reggie Miller big-time
