I jump right back like 36,
“Jump back” refers to the amount of crack cocaine that can be made from cocaine powder. Therefore, if the jump back was equivalent to 36, this actually describes the purity of the cocaine in question. Cocaine that has been cut with other substances (“stepped-on”) to extend its volume would produce less crack on the jump back. (Note: It is physically impossible to synthesize a mass of crack cocaine equivalent to the initial mass of cocaine powder. The miracle of science…)
Meek could also be referring to former Philadelphia Eagle runningback Brian Westbrook (#36) who was known for his running style that included a lot of cutting back . .
