Yeah but you could go all the way back to 1979 and rapper's were lying in their raps. Big Bank Hank said he met Lois Lane and that he had more clothes than Muhammad Ali.
Rap lyrics are hyperbole, you're supposed to rap about how much money you have, how many cars you own, what your mansion looks like, how women throw themselves at you, how much weed you smoke, you only drink expensive champagne, you wear designer clothes, and your relationship with your butler, maid, chauffeur, and private chef. If you're good at rapping about those things and you have hot beats you can be a star!
