Early life
Markeyvius LaShun Cathey was born in South Memphis on August 3, 1997. When he was 20 months old, his mother Tameika Cathey was sent to prison, where she would be for the next 15 years. His father was in and out of his life, so he was raised by his grandmother and his aunt. According to Cathey, he and his grandmother occasionally visited his mother in prison during his youth. At 18 years old, he was charged with three counts of aggravated assault related to his involvement in a shooting. Music was a distraction from his oftentimes tumultuous life.

Cathey said he grew up listening to Gucci Mane, Lil Wayne, and cites Three 6 Mafia as his largest influence. He was also a big fan of Project Pat, whom he describes as the "Drake of Memphis". According to Glock, Pat's songs "If You Ain't From My Hood" and "Gorilla Pimp" changed his life. The latter's chorus inspired one of his breakout songs, "Dig That". The first track that Glock recorded himself was a freestyle of DJ Drama's 2011 song "Ain't No Way Around It".
