Following in the footsteps of “drip” and “no cap,” the ad-lib “slatt” recently emerged as a popular hip-hop slang term. Although it’s frequently associated with Playboi Carti, “slatt” should actually be attributed to his fellow Atlanta native Young Thug. According to Genius data, Thug was the main rapper using “slatt” from 2013 to 2016, dropping the ad-lib in 15 different songs.
