Summerween is an informal cultural and retail phenomenon that blends Halloween festivities with summer celebrations. The term originated from the 2012 Gravity Falls episode titled "Summerween," where the fictional town of Gravity Falls celebrates Halloween twice a year, specifically on June 22 because the residents love the holiday so much.
For example, the inhabitants of the town carve "jack-o'-melons" instead of jack-o'-lanterns.
