i actually thought that there was a 7 year old gang member on his tv. is blood a new slang for beef or something?

I think it’s “a 7 year old” “blood walking” … Back in the day it used to be “crypt walking” and the bloods and crypts were rival gangs.

Anyway blood/crypt walking is a “dance”. Think of it like almost a jig or skanking but gangster style.
