Red Saturday
n. The day after Black Friday

Black Friday, given its name because companies finally find there business "in the black" for the year, has given birth to Red Saturday; an unintended side effect. Holiday shoppers, blinded by the numerous sales often awaken a day after their shopping spree to find there bank accounts severely overdrawn or "in the red"

red saturday festivities usually include arguing with significant others, locating sales receipts, returning items, and sleeping alone
Wife: I hear Best Buy is having a great Red Saturday special.

Husband: sounds great honey.
Wife: yeah, if you return those 2 fifty inch flat screen tv's, u won't get murdered you in your sleep.
