Thumb through that check, make sure its adding up
Thumb through that check, rubber band then bag it up
Thumb through that check, I don't know yo ass like that

from Rick Ross – Thumbin' Lyrics on Rap Genius

Rocko checks to make sure all the money is there, throws it in the bag and explains that he isnt trying to disrespect you, he just doesnt know you well enough that you wont short him
