Krush Groove 1, 2, 3, & 4?

[BangBangBunny]

At the risk of sounding like an idiot, although it's probably too late:

Sucker MCs = Krush-Groove 1
Hollis Crew = Krush-Groove 2
Darryl and Joe = Krush-Groove 3
Together Forever = Krush-Groove 4

Does anyone/everyone know why they get those sub-names? Were there only 4? Word...

Peace,
BBB
