What is the "Bruiser"?

I've read posts where people talk about the "bruiser" a couple of times now, but can't find any info on the actual exercise and how it's done.

I'd appreciate an explanation thank you.

The Bruiser, or Bruiser 180 as its sometimes known, is a potentially danderous excercise that should be avoided. It involves twisting your semi erect penis 180 degrees and then holding it in that position between your thighs. It is supposed to add girth to your penis, but you are risking tearing the underlying tissue.
