Gold medalist in the back shot
Hip-hop has already been called “Olympic sponsor of the black glock” — the best interpretation is that this line follows on that one, continuing both the Olympic and gun metaphors.
“Gold medalist in the back shot” would mean, in this context, that hip-hop is a past master at cannibalizing its own, through both literal violence and industry back-stabbing. “Back shot” would be read as the equivalent of “a gunshot in the back.”
Some have suggested that “back shot” here is a reference to doggystyle sex. The context makes this seem less likely (“Olympic” goes with “gold medalist”, so there is reason to think that “black glock” goes with “shot”), but it is certainly possible that Mos is referencing hip-hop’s obsession with explicit sex, as exemplified by artists like 2 Live Crew and Too Short.
