It was all a trap, yo as you 'bout to find out. Jay G is CEO of Obsidian! Bioootch! Now your bank account is withering, your bottom lip is quivering, you're Hufflepuff, I'm Slytherin, there's no one doin' your Smitherin'. This is where your money went, evict you from the one percent, now watch me as my fingers tent, 'cause I own you, it is excellent!||„|
