50 Cent is a pussy nigga he only start shit with individuals that can't hold they own.
To name a few
Crooked I, Hussein Fatal, Nas, Nore, Eastwood, Memphis Bleek, Bobby Brown, Dj Kay Slay, Missy Elliot, Jayo Felony, Shade Sheits, Lil Mo, All did songs with JaRule and I don't see Curtis fucking with them.
I know Bobby Brown would physically beat his ass. and Crooked I, Nas, Fatal would lyrically tear him down.
