And whoever and that mothafucka
Nasty new street slugger,

from 2Pac (Ft. Outlawz) – Hail Mary Lyrics 1 on Rap Genius

Meaning

Young Noble is saying that he’s ready to put an end to any competition, specifically Nasty Nas.

2Pac (although this verse isn’t sung by him) dissed Nas on his song Against All Odds.

Extremely interesting fact: Nas cried when he heard the diss from Against All Odds(source). He is also a huge fan of 2Pac.
