On NBC's "Parks and Recreation," characters Tom Haverford and Donna Meagle participate in an annual "Treat Yo'Self" day where they can buy whatever they want — clothes, fragrances, mimosas, massages, fine leather goods — no matter the cost.

Although the show's last "Treat Yo'Self" episode aired in 2015, the phrase has become synonymous with luxuries and impulse purchases. Do you really need a new watch or another handbag? Who cares? Treat yourself.
