How are pirus and bloods different.

This is what I found on the internet: Original formation of the Pirus Street Gang ... At one time some members from the Pirus were a part of the Crips before they broke off from the Crips and became some of the first gangs within the Bloods. There is disagreement whether Pirus and Bloods share the same usage.

Pirus are one part of the whole Blood movement
