Charles Oakley to Game 7 Security: 'Touch Me, See What Happens'

Charles Oakley was PISSSSED while waiting outside of the Cleveland Cavs locker room after Game 7 Sunday night -- at one point telling security, "Touch me, see what happens."

The 52-year-old NBA great is a Cavs fan -- he's from Cleveland -- and we're guessing he was waiting around to celebrate with the team.

But something went awry -- as captured on video by USA Today's Sam Amick -- and it culminated in Oakley essentially challenging security to step up ... or shut up.
