Terrance Michael Boykin (born September 15, 1979), known professionally as Bump J, is a Chicago rapper who adopted the name Bump J, an allusion to early 20th century mob boss Ellsworth “Bumpy” Johnson, the main Harlem associate of the Genovese crime family.

He was once signed to a big deal with Atlantic Records in 2004 but never released an album. His career was on hold from 2008 to 2017 after getting sentenced for an armed bank robbery that happened in January 2007.

The following year in 2018, he would release two mixtapes: March’s 606 God and June’s I Don’t Feel Rehabilitated. In 2023, he would appear on the track “VULTURES” with Kanye West, Ty Dolla $ign, and Lil Durk.
