Another day, another social media beef. This time, it's Bow Wow and Funkmaster Flex going at it on Twitter.

On Tuesday (Dec. 13), Funk Flex kicked things off by tweeting, "FYI- Bowwow is Fucking finished out here! FACTS! His records is trash! Basura!" Bow Wow quickly replied with the Twitter poll, "Should @hot97 fire funk flex and hire NEW FRESH Hungry dj's from NYC?"

At one point, Shad posted an old advertisement of Flex for Lugz, with the caption, "NYC y'all approve of this? A fake screaming dj who blows kisses and wears lug boots 😂 #Firefunkflex." You can view the rest of the back-and-forth tweets in the above gallery.

Of course, Flex is no stranger to rapper beef. Just the other day, the Hot 97 DJ said "Fuck Drake" while playing Meek Mill and Tory Lanez' "Litty" during a set. “Fuck Drake. That Internet shit, he don’t give a fuck," Flex said. "He don’t come to Brooklyn, not at all.”

Bow Wow is no novice to beef, either. Back in September, there were issues with his ex-girlfriend, Erica Mena. Prior to that, when Shad said he was retiring from rap (he has since returned), Lil Romeo posted a heartfelt message, touching on his past beef with Bow Wow.
