Sep 25, 2016 Metro Boomin sent out a series of tweets in which he called out artists who tried to emulate Future and his success. Thugger assumed the posts were directed at him, so he began going in. Hey @MetroBoomin who u referring to ???? — Young Thug ひ (@youngthug)November 10, 2015 A n----- music couldn't ever sound nowhere near mines.... ((IM MICHEAL)) he's ((TITO)) — Young Thug ひ (@youngthug)November 10, 2015 The beef was re-ignited earlier this year, when Young Thug told Future to "slow down dropping all that BS music." Future replied, of course, and another “internet argument” ensued. Yo b---- wish u was me...in real life — FUTURE/FREEBANDZ (@1future)February 3, 2016 Yo family/team wish u was me lil n-----.... — Young Thug ひ (@youngthug) February 3, 2016 RELATED Listen to Metro Boomin's "Chanel Vintage" f/ Future & Young Thug Is Young Thug Taking Shots at Future on Twitter? Young Thug Threatens Metro Boomin: "[I'ma] Beat the S**t Out u Fool" Months later, the rappers appeared to be on good terms, as they collaborated on the track "Who" off Future and DJ Esco’sProject E.T. The two also posted Snapchats last week that hinted at another collaboration. Clearly, they've been over the beef for a while, but Thug still had enough respect to send out a public apology. Maybe other rappers should take note.
