This video is from back in 2013. It shows an American writer of sorts, named Gene Gregorits, cutting off his own earlobe and swallowing it.
I’ve heard he was high on bath salts when he did that, but there are also some who say he ate his earlobe in order to promote his books by drawing attention to himself. The truth could be the combination of both.
Props to Best Gore member @uncuckyourself for the video:
