Angry girlfriends are finding the perfect way to shame their love rat exes - on YouTube. The craze for publicly humiliating cheating boyfriends has reached new heights, with hundreds of postings on the video sharing website.

Some have followed the extreme example set by a British woman called 'Costacarta' who filmed herself getting intimate with a gigolo to make her boyfriend jealous.

Others have sought revenge using more creative techniques. One of the most amusing (unless you are the victim) is a song dedicated to her ex by 16-year-old Caitlyn Bush, from Ohio, called All The Small D***s.
