Waka Flocka clarified his recent remarks characterizing himself as a "wack rapper" saying that it was a form of "reverse psychology." During a conversation with Rap-Up TV, Waka said the comment was a ploy to get others to admit that he had an influence on them. 

"It was more reverse psychology, [...] It was more so of this generation and the people that got power and feel that way—You know I be seeing make these little lists that say 'Influential people of the decade.' And I be sitting here like, 'Yo, hip-hop never sounded like this before me. Who's more influential than that? Okay, cool I'mma wack rapper I guess.' Let me say I'mma wack just so y'all can actually hear people say 'No this guy's actually the GOAT—one of the GOATs—I'm not saying I'm the GOAT. I actually be sitting next to them by default."
