Rex 

A nigga and a person who Ludacris wants to slap.

I know it's strange
But my brain's gone really insane
And I'm off the chain
Sipping on a fifth of the Golden Grain
I feel like slappin a Rex today (slap slap)
Slappin a Rex today
I feel like slappin a Rex today (slap slap)
Slappin a Rex today
Slappin a Rex today
