hey i had a few questions

What is meant by fifth-form disco ?
What is meant by gory details ?
This is what I understand it as. The first one depends on the context.
Fifth form can be a school year of those aged about 15. It's normally the third to last year of schooling (depending on the country). Sometimes a scool has a school disco (non-alcoholic or course) for all those at the fifth or sixth of seventh form level.
Gory details are ALL the details without exceptional. Normally when you don't want any details excluded. Also it can mean that the details are grotesque, bloody, like someone talking about the results of a car crash.
