There's another rap beef steeping, and it all started on social media. Yesterday (Aug. 11), Soulja Boy threatened to kill Philly rapper Gillie da Kid for speaking ill of him and his allegedly fraudulent jewelry on Instagram. 

After SB threatened to slap Gillie, he fired back in an interview with Forbez DVD warning, "You don't want me to slap blood in your mouth n---a. You better go on Twitter and say you sorry to the OG, n---a."

Soulja Boy went "back on Twitter" alright, only not to apologize. "I swear to God umma kill you i don't care what i gotta do but umma do it," he wrote. "You got me f----d up on my lil bro grave I promise."

Gillie clearly upset the 24-year-old rapper because the tweets kept coming. "You a b---h. But I'll see you soon tho. @gilliedakid f--k boy," he added. "Tired of these washed up old a-- rappers looking for a 2nd chance. Can't wait to kill this n---a."

He then boasted about his involvement in a "shootout" and made plans to visit Gillie in the City of Brotherly Love –– as soon as his schedule clears up. "Umma shoot that n---a right in his bald head. On God. we gonna see. I'll be in philly ASAP soon as I finish getting this money tour."

Soulja Boy's tweets have been deleted and replaced with Vines about being high and promos for some of his new music.

Gillie wasn't silent through the Twitter fight. He accused Soulja Boy of "snorting a whole 8ball" and pretty much laughed at his threats. He also used the extra Twitter attention to plug his mixtape, King of Philly 3.
