Jacquavius Dennard Smith[2] (born May 1, 2000), known professionally as 9lokkNine (pronounced and formerly typeset GlokkNine), is an American rapper and convicted felon from Orlando, Florida.

During his youth, he had aspirations of becoming a footballer, a prospect which was halted due to his numerous legal encounters as a teenager.

His stage name was derived from friends giving him the nickname "Glock", referring the pistol's reliability to Smith's "grind and determination".

As a result, "223's" peaked at number 34 on the Billboard Hot 100 and received double platinum certification by the Recording Industry Association of America (RIAA).

[12] In September 2015, Smith, who was 15 years old at the time, was arrested in connection to a shooting that left a 17-year-old hospitalized.

[15] On January 3, 2020, Smith was arrested in Miami, Florida, and charged with carrying a concealed weapon.

[20][21] On December 15, 2021, Smith was sentenced to seven years in federal prison after pleading guilty to identity theft and possession of unregistered firearms charges.
