"Umm Hmm" is an aggressive and violent track where YoungBoy Never Broke Again spits what's on his mind. He threatens his foes, naysayers and even anyone who touches his jewelry.
Beatmaker HitmanAudio and recording engineer Khris James created the fierce production.
YoungBoy recorded "Umm Hmm" for The Last Slimeto while he was under house arrest for possessing a firearm and ammunition as a felon. According to Kris James, the Baton Rouge MC laid down the entire song inside his Tesla.
Despite not being released as a single, "Umm Hmm" was the only Last Slimeto track to debut in the Top 40 of the Hot 100.
