Carolina Panthers quarterback Cam Newton left Auburn for the NFL draft after winning the 2010 Heisman Trophy, but that doesn't mean he's out-grown the hate between the Tigers and rival Alabama.

During his time at Auburn, Newton was surrounded by allegations that he accepted money to play for the Tigers, and those rumors haven't been forgotten by the Crimson Tide faithful.

Newton, in Auburn Saturday for the 2015 edition of the school's "Iron Bowl" rivalry, was hit with a "180K" chirp by an Alabama fan, and yelled back: "I'll slap the s--- out ya."

There's a reason this rivalry is thought to be among the most heated in sports.
