Sean John Combs was the catalyst for this movement considering his involvement with his nemesis Suge Knight. Peep..
He was called out for dancing and being in his artists' videos too much and always wanted to be in the spotlight, but really never had the talent for the mic....until Biggie started to write for him during the recording of his Life After Death (songs like "Player Hater" for prime example) album and start of the No Way Out album and Jadakiss, who was forced to write for him (his verse "Victory") and other songs, in which Jada was hesitant to write for Diddy...because deep down Jada knew he was wack..but somehow, he was coerced (promises of money, fame but ended up being one of the 1st artists on Bad Boy to get financially raped) and eventually ended up writing for him.
Hearing songs about being how being a hater was negativity and how it prevented you not getting paid like him or others like him became the norm throughout...which was the start of the Jiggy Era of Hip Hop. Rapping about lavish living, big bank accounts, fucking dime models and being high profile was all Diddy..Big basically was rapping through Diddy until he got it and it became somewhat a cancer. It was always done, but not until Bad Boy made it into a sub-culture itself...then it trickled down to Ma$e, and Jay took the baton...well you know the rest afterwards.
After Big got killed the No Way Out gave Diddy the space he needed to vent out to those that had a problem with him from dancing in videos, having his hands deep in his artists' craft (and pockets) being a rapping executive who couldn't rap but write big checks to have other top notch MC's write for him. This itself was a problem because due to Puff's success it made it open for those who couldn't rap and was wack and live out their dream..especially if they were executives, i.e. Jermaine Dupri, Master P, ..and them signing acts that were wack and there you have it.
