The 'Yoo-hoo! Big Summer Blowout!' meme originates from the 2013 Disney animated blockbuster Frozen. It features the character Oaken, the jolly proprietor of the Wandering Oaken's Trading Post and Sauna, as he enthusiastically offers a discount on winter gear during a sudden summer cold snap. The scene became an instant favorite due to Oaken’s distinct accent and cheerful demeanor. In internet culture, the template is widely used to celebrate actual seasonal sales, mock overwhelming amounts of information, or humorously highlight ironic timing. Its versatility makes it a staple for both retail marketing and relatable everyday social media humor.
