Sister's Slam Dunk () is a South Korean reality show that aired every Friday on KBS 2TV from April 8 to December 2, 2016. The show's first season featured an all-female cast consisting of Ra Mi-ran, Kim Sook, Hong Jin-kyung, Min Hyo-rin, Jessi and Tiffany, and followed their attempts at fulfilling each cast member's dream using a budget of â©2,196,000 or approximately $2,000.
The cast members formed a special girl group named "Unnies" () and released a Park Jin-young-produced single titled "Shut Up", featuring You Hee-yeol, in July 2016.
Season 2 of the program focused primarily on the girl group project, which was Min Hyo-rin's dream in season 1. The show followed seven members, Kang Ye-won, Han Chae-young, Hong Jin-young, Minzy and Jeon Somi, with Kim Sook and Hong Jin-kyung returning, as they formed the second generation of "Unnies", produced by Kim Hyeong-seok (Park Jin-young's mentor). The fulfillment of each member's personal dreams have become the side projects of the program. The fan club name for the group remains as "Dongsaengs" (i.e. younger siblings) and their official greeting, as suggested by Heo Kyung-hwan, is "Shoot! Shoot! Shoot!, Hello! We are Unnies!", with an emphasis on the basketball shooting motion while saying "Shoot". Their official fandom object is a denim-colored balloon.
Sister's Slam Dunk follows the "Real Variety Show" format where the content is mostly unscripted. Additionally, there are no signature segments within the show, as it focuses on completing a single major objective over the course of several episodes. In resemblance to a reality show and a documentary show, each episode also documented their activities together and the relationship between the members. In season 1, the overarching theme of the show was the fulfillment of each member's dreams. Every episode focused on accomplishing several tasks that would lead to the fulfillment of those dreams. The members' dreams are, in chronological order:
In season 2, the format remains as "Real Variety Show" without a scripted segment and follows the members' activities across a certain period of time. However, the theme of the show focused on the continuation of the girl group project, "Unnies". The content for each episode chronicles the members' progress towards releasing songs and training for their stage performance. Similar to season 1, each episode documented their activities for a couple of days and their bonding as group members.

On August 14, 2016, (the day before Korean Liberation Day), Tiffany posted photos on Instagram and, a day later, onto Snapchat that included the current Japanese flag and the Rising Sun design which was part of a Snapchat geo-filter respectively while performing in Tokyo as a part of SM Town Live World Tour V. Although she had taken down her Snapchat post within minutes after posting, she faced substantial criticism, and she deleted the Instagram images soon after as well. The program received an outpouring of complaints demanding for the show to remove Tiffany. On August 18, 2016, the program announced that after discussing the situation with S.M. Entertainment, the decision to withdraw was reached. The official statement reads: "As a result of the discussion, we have the final decision for Tiffany to leave the show, in consideration of what we agree to be the effect that the controversy had on the country's sentiments." However, in December 2016, Tiffany reunited with the other cast members at the 15th KBS Entertainment Awards, where they opened the ceremony by performing "Shut Up".
