Another word for "bedtime", first taken from the Simpsons' episode where Lisa tells Bart to go to bed, but Bart mishears her as saying go to bread.
Lisa: Go to bed!
Bart goes to the kitchen and eats bread.
Lisa: WTFGTFO GO THE FUCK TO SLEEP!
Bart: Oh, "go to bed"! I thought you said "go to BREAD"!
Thus it was breadtime for Bart.
