Stands for take it to the floor, it’s some Greek life dance/performance thing they do and different frats and sororities are paired together, I think it also raises money for charity or something

it’s a sorority and fraternity charity event called “take it to the floor.” sororities and a frats get put partnered up and they do a dance together. Theres also themes like for example broadway musicals.

yeah it’s basically the super bowl for greek life every semester. themes and teams are made before the semester starts and they raise $100k for the event throughout the sem. huge deal for everyone in greek life and otherwise just fun to watch
