A philosophy by the late 2Pac that in the quest for power, one must always keep his pursuit of money above his pursuit of women. The example used was if someone focuses on chasing women, they will only stick around until another either richer or better looking man where to come along. But if one puts money before women, he will get all the women, while simultaneously remain rich and therefore powerful.
The late Tupac Shakur defined the fraze M.O.B to mean 'money of bitches', although this definition had a meaning of its own, what tupac actually ment when he said it was that he was now MOB related, i.e, a Member Of Bloods. The Bloods are a west LA street gang.
Therefore the fraze is actually a clever double meaning.
Some rappers still use the fraze 'MOB' to mean Tupacs defined meaning 'Money Over Bitches' without knowing what he was truly implying.
"I heard steve is now a M.O.B"
"Get rid of that girl, M.O.B"
