The act of being extremely fly, doing unexpected/extraordinary things. Going above and beyond, balling out of control. Doing it cars real big, house real big is having an excessive amount of panache. Doing it bigger than anyone already has.
OC, Last weekend I was with my boy Juicy J; he brought down seven girls for the two of us, and ten bottles for the night; everytime he throws it down, he's doin' it cars real big, house real big.

We be doin it cars real big, house real big, know what I'm saying? I just put that 52" flat screen on lock, got five kegs on their way, hired 10 strippers, and rented out the prezidential suite baby!
