The long-running beef between Shaq and Golden State Warriors player Javale McGee was taken to the next level on Thursday when Mr. O'Neill threatened McGee with physical violence via Twitter.

After Shaq promised to "slap the s**t" out of McGee when the 29-year-old told Shaq to "keep my nuts out of your mouth," Kevin Durant came to the defense of his teammate while speaking with reporters on Friday.

Regarding Shaq's threat, KD said, "I didn't know cops could threaten civilians." Shaq is a sheriff's deputy in Clayton County, GA.

Shaq wasn't going to take the diss unanswered, however, and he quickly hopped on Twitter to fire back at Durant. "@KDTrey5 mind yo business this ain't for you," he wrote.
