MGK took to his twitter saturday and advised his hardcore “rage” fans to meet him at the local South Park mall in Cleveland in hopes of pulling off a flash mob stunt.However the Clevland police dept got tipped off and were ready for the rapper to arrive.They did atleast give MGK the chance not encourage the crowd by standing on a table with his megaphone,but MGK decided to say f*ck the police and did it anyway.See how the rest plays on in this captured video of the event.
