Ever since Tyler, the Creator threatened to "crash that f*****g airplane that f***ot n***a B.o.B. is in" on his viral single "Yonkers," (a reference to B.o.B.'s hit single "Airplanes" with Paramore front woman Haley Williams), it's safe to say B.o.B. hasn't exactly been an Odd Future fan.
The Atlanta rapper, who received five Grammy nominations for his debut album The Adventures of Bobby Ray last year, retaliated in late March with a track called "No Future" that contained a number of veiled jabs at Tyler and his crew. Responding to the song, the Odd Future leader downplayed the beef via Twitter.
"Whoa, I don't think the "No Future" song is even a diss. But, I've never heard him spit like that. Took me by surprise, cus its tight. Still hate that Airplanes song tho," he tweeted.
But apparently B.o.B. still has more to get off his chest. According to Complex magazine, the "Nothin On You" rapper uses a guest appearance on Tech N9ne's upcoming album, All 6's and 7's, to take more shots at Tyler.
The song in question is called "Am I a Psycho," and B.o.B. reportedly gets heated on the track's last verse, never mentioning Tyler or Odd Future by name, but dropping subliminal disses that Complex likens to Eminem taking down Benzino.
He may seem non-threatening on his singles, but it looks like B.o.B definitely bites back. Expect more back and forth when the track officially makes its way online.
