Born Omar Jermaine DeClark in 1998, he always had a dream to rap, growing up listening to Eminem, Lil Wayne and Kanye West. On his 20th birthday, he decided to start recording tracks and released his first song, Ice On My Wrist, on March 6, 2018. After gaining a small fanbase off this song, he released his debut album, Ice!, on April 19, 2018. These songs featured on the album took a silly approach and after gaining more fans, Lil Flexer started the Old Man Dad Records label and signed one of his childhood friends, Lama Doodle, to the label. Lama signed fellow rapper Submarine Man to the label. Flexer appeared on Submarine Man's debut album NoStockingz. After Flexer dropped his single Pay Day, dissing Canadian rapper Drake, and announced that his music would be taking a more serious approach, Submarine Man criticized him for the Drake disses. Submarine Man released his The Bad Boy EP, featuring three Lil Flexer diss tracks. Flexer responded with Talent, featuring Yung Spiderboi55, a brutal response to the Bad Boy EP. On November 3, he announced that his second album "Flexer For Life" would be dropping on November 16, 2018.
