As Def Sounds previously reported, Cassidy stepped up to the plate when Meek Mill put a 100K rap battle offer on the table. When Cassidy accepted the challenge, Meek eventually backed out, which led to a war of words late last night on Twitter.

Cassidy and Meek Mill exchanged words after Cassidy tweeted that he paved the way for Philadelphia artists.

Meek wasn’t feeling Cass’ proclamation that he paved the way for Philly rappers, and started to go in on Cass over the social network, which caused to Cassidy to head right to the studio and record a new diss track aimed at Meek Mill.

Check out the series of tweets from Cassidy and Meek Mill, which led to Cass hitting up the studio and going in on Meek below.
