Yeah the "when i was just little baby boy..." part is an INTRO
The "Bitch i'ma kill you, you don't wanna fuck with me..." is technically considered a HOOK (in rap terms the CHORUS is often referred to as the HOOK)
The "I said, you don't, fuck with Shady!! Why not??? Couse Shady will fucking kill you!" is actually the CHORUS
In simple terms the HOOK is what connects the verse to the chorus hence it "hooks" onto the chorus
the BRIDGE is what "bridges" the gap between a chorus and a verse (and a bridge is usually only in a song once"
and i'm sure we all know what a CHORUS is
please correct me if im wrong though because im no music expert
