Vic Mensa has some serious words for Brooklyn rap phenom Tekashi 6ix9ine; fight me in a one and one and according to the Windy City rapper, it won’t go well for Tekashi.

The Roc Nation representative went to his Instagram page today and offered up to square up in a “one on one” after Tekashi got at the Chicago rapper for claiming that the “Gummo” emcee needs to show Chi-Town some respect.

Mensa says that Tekashi’s style is rooted in Chicago’s “drill rap” culture.
