ATL rap star Ludacris reportedly took aim at Big Sean and Drake on his new mixtape, 1.21 Gigawatts: Back To The First Time, verbally assailing the two young MCs for disrespecting him and claiming to have invented the so-called "supa dupa" flow or "hashtag rap."

In an interview with KUBE 93 radio in Seattle, Big Sean admits that he may not have been the first person to use the style, and says he has nothing but love for the veteran hip hop star.

"I ain't got no problems with Luda, I never did. I think he's referring to an interview I did over a year ago. Literally over a year ago. But in the interview I said he's a legend," Sean said.
In an interview with MTV RapFix in March of this year, Big Sean spoke to Sway about the flow in question. Drake, who popularized the technique on several songs in 2009 and 2010, had been quoted making disparaging remarks about Ludacris's attempt to use it on his own single, "My Chick Bad."
“Coming down the street like a parade — Macys,” Luda rhymed.
“I think some artists just did it so wack, man,” Big Sean said at the time. “Every time I say names I get in trouble and it’s like I’m dissing, but some people used it wack. If [Drake] said Ludacris used it wack, hey.”
In his defense, Sean did backtrack from the implications of that statement almost immediately.
“Don’t get it wrong, I’m not trying to dis Ludacris or nothing. He’s a great MC," he said in the same interview.
Ludacris, however, apparently wasn't comforted.
“Counterfeit rappers say I’m stealing they flows / But I can’t steal what you never made up, b----! / Y’all some duplicate rap-cloning n***s ," he spits on the song, "Badaboom," from his new mixtape, clearly referring to Big Sean and Drake.
“Eleven years and still counting / And y’all get a couple of hit records, make some noise and have the nerve to start shouting?” he continues. “You lyin’ to yaself, just admit it / May not like the way I used it, but you know you ain’t invent it, boy / Do your research before you make a claim so bogus that’s disrespecting pioneers in the game.”
Speaking with KUBE 93 about the diss, Sean admitted the supa dupa flow probably predated both him and Ludacris, but said he was the one responsible for its current renaissance.
"I'm pretty sure it was done before [Luda] but I'm just saying where it came from now." he said. "We talkin' about now … I'm not trying to debate and say, 'I was the first to do this ever.' I'm just saying that's just where it was between us."
Despite all the harsh words, however, the "Finally Famous" rapper reiterated his love for the elder emcee.
"I don't have no problems with Luda. I didn't even know he cared that much, for a year, to be thinking about what I said in interviews … I think Luda is the best, I think he's a legend," he said.
