Jules Crittenden has a good analysis a href="http://www.julescrittenden.com/2010/04/28/sexual-violence-against-men/"of why men are hit in the groin:/abr /br /blockquoteIf I had to get Freudian or Jungian or whatever about it, I’d say it has something to do with humiliating a patriarchal power figure in the place where his power resides, as an expression of rebellion, resentment to the suppression of matriarchal blah blah blah and as retribution for any prior and future offenses anyone of the offending gender may commit. But I suspect most ball-kick humor is actually perpetrated by men, which makes me more inclined to get Goodallian about it. As any chimp could tell you, kicking the alpha male in the balls is good fun if you can get away with it but beating up mom is bad form./blockquote
