Still Not a Player Capital Punishment Big Pun

couldn't measure my dick with 6 rulers

He saying in this sentence that he has a large penis (larger than 6 feet)
Shinobi Shaw
Big Pun is proclaiming that because his penis is so long, over 6 feet long in fact, even 6 rulers laid on end would fall short of giving an accurate measurment of it. Unless he is refering to 6" rulers in which case it could be barely over 3feet long
