Witnessed several conversations (mainly between boys) laughing about the fact that one boy had kissed a girl at a party who was not in a state in which she could consent. This was treated as a joke in which the punchline was how forceful the guy was and how disgusted the girl looked. The joke was perpetuated for over a year. In another conversation boys made inappropriate comments about a girls genitalia which was exposed when she was passed out. When I was in year 12, a student in the year above made a list of the girls in year 12 with the best arse and tits. This list was common knowledge within the whole sixth form and was the subject of many conversations in which the girls on the list were routinely objectified.
