He's talking about some club music shyt. Mind you, this has been going on since last year, lol. Basically, the argument is Philly acts like they invented rapping over club beats when that shyt has been part of North Jersey culture for like 15+ years. Not even the whole North Jersey, mainly in Newark and East Orange. Now everybody wants to act like they been on it since it's the sound right now when they know and we know that was not the case.
Most people in NY and Philly thought club music was just some "weird Jersey shyt" but now everyone is hopping on the wave thanks to Tiktok. Philly really can't even argue against this because a Jersey nikka literally produced the Lil Uzi "I Just Wanna Rock" record, which is their biggest song right now. That's the part a lot of people hate lowkey because they can't debate that fact. That's why you see a lot of young people from Philly going full retard on Twitter talking about "we created this shyt" but they don't even know the history. They hate that a Jersey nikka played a part in their biggest record but they already stamped it before they found out, now they just saying fukk it we pioneered this whole movement lol.
