In your opinion or other peoples?
Mine is when I was around 18/19 a guy I was seeing had been messing me around and then decided not to contact me again.I saw him in a nightclub a few months later and he tried to chat me up again,acting interested.When I was on the dancefloor later on I saw him watching me and beckoned him over.Just as he approached I grabbed a good looking man and snogged his face off right in front of him,leaving him stood there.It felt so empowering at the time and I've never done anything like that since.
