Well that didn’t take long. After hearing Cassidy’s recent diss track, “Me, Myself and Iphone,” Meek Mill took to Twitter to address the song.

“Listening 2 this diss,” he tweeted. “Ima say cuz you lost ya mind! U really gone up top mentally …… I feel sorry for u! Lol When me and @CASSIDY_LARSINY was locked in the same jail!!! He was on “PC” protective custody …. I was on the “drama block” #difference. Ima let em b great tho! ✌”Stroke em condom style” lol Then @CASSIDY_LARSINY u got booked for a body u ain’t do and took a deal on ya co-defendant….. Left him for dead! Halfway telling!”

After trying to crush Cass’ character ever further, the MMG rapper finally obliged Da Hustla's battle offer at least on paper computer, adding, “After tomar I don't wanna hear no more about it.... #mmg #dcr ...Then we can donate the money 2 the schools they Tryna close ….. Our city need it….lets do it tomar! U don’t even come back home! Lets stop tweeting and give the fans what they want tomar …. I’m done…this when u don’t get time 2 write raps …and we gone donate”

Cassidy then replied, "Me, Myself, & iPhone" all he do is tweet.. I get in the booth & put pressure on niggas.. That Lil run ain't last long! It's ovr 4 niggas." Before adding, "I gave @MeekMill months to respond.. Tomorrow? I thought you wasn't battling.. FOH That song got you tight!!! Step them bars up..”

So, is it on?
