T.H.U.M.P. was born Jeffery Leon Toney on March 10, 1981 in the city of Oakland, California. Although Oakland was his hometown - he never had a stable place to call home. At one point in his youth he bounced between several hotels along the Mac Author Boulevard Strip - a street well-known for prostitution and heavy drug trafficking. "Raising two kids in a single parent home is tough enough. Being jobless made it seem impossible, but my mother did the best she could," says T.H.U.M.P. crediting his mother for her strong will through his adolescence. At the age of ten, T.H.U.M.P. was sent to live with his grandmother. This move allowed him to run free in the streets of Oakland where he got involved with neighborhood peers and formed a clique.
