So who you named shouldn't be mentioned with us
But wait, at least half of em', other half rapped around

from Joe Budden – Lost Control (Freestyle) Lyrics on Rap Genius

Meaning

Joey isn’t offended by Kendrick not name-calling him, he understands because most the rappers in the game are WACK and it would be offensive to mention these rappers with him and his crew (slaughterhouse).

In the same vein, Joe is saying at least half of the rappers
Kendrick named are on his level — referring to the names Kendrick mentioned first — Nas, Jay-Z and Eminem.
