Originally a secondary school qualification 'equivalent' to an Alevel. The term has changed meaning to describe something so pathetically stupid, it can only be described as BTEC
Luke: Dude have you seenAlan's gaming setup, he's playing with a trackpad.

A thing that tries to be another thing but is considerably worse that the original. (Originally comes from the inferior qualification that UK students can choose to take instead of the much better GCSEs and A-Levels)
