A time at the end of the week where bros get together to discuss important subjects and congregate in sexually appealing activities. These activities could include Game of Thrones, Gears of War, Yu-Gi-Oh, Pandemic, midnight Macs runs, or nacho making. Also, forking.
Bro #1: Dude, it's Sexy Friday!
Bro #2: What are we gonna do tonight, bruv?
Bro #1: Gears and Thrones, obv!
