There is a time of life when everyone writes down the names of all the girls in the year and then award points for their key features. Attributes such as "breasts", "arse" and "face" were all judged and graded. We also had a category for whether she was a slag or not - higher points obviously awarded for slags. We kept our top trump chart fairly quiet, but by the time it had been handed down to my brother's year, they actually drew individual cards for each girl, had them laminated and would then sit and play "Girl Top Trumps" in the middle of the class each lunchtime.
