This week 
50 Cent mocked his baby mama 
Shaniqua Tompkins for getting plastic surgery back when they were together [click 
here if you missed that].
Welp, Shaniqua is NOT playing with 50 and just fired back with a shot below the belt...
...literally by mocking 50 about having genital herpes.
FYI: DJ is 50's other baby mama model Daphne Joy.
