Well, that's certainly a leap from the middle classes (that's it, Laura, I'm done with Waitrose, from now on I'm shopping in Lidl and I'm doing it drunk and in quite probably in heels. I may even be sick in the freezer, right there, atop the petits pois*) right into the elevated echelons of the upper classes where a boisterous defloration is, one supposes, de riguer for a certain sort of Cambridge student. Not the token ones from state schools, of course. Ritual deflorations, for those of us less enlightened, involved the restricted confines of a mid-1980s Ford Fiesta.
*there, I've saved you the trouble of reading The Animals.
