Rappers saying that subliminal disses aren't about anyone in particular

Examples: Drake on "Dreams Money Can Buy," Pusha T on "Exodus" and "Don't Fuck With Me," T.I. on "I'm Talkin' To You"

You might be a rapper if... you've compiled a group of rap enemies and in an effort to really hit them hard, you put a lot of time and effort into crafting the perfect put-down. Your goal is to shame them on the highest level, and send them into a deep, dark place where they'll never recover. You'll do anything it takes. Anything, that is, besides actually mentioning their name.
