another Glee post!

I was re-watching some Glee episodes for another module and I realise Glee has many new and interesting lexical items. So here's 2 more:

diva-off and glee-off - used in the same way as faceoff (an open confrontation, courtesy of Dictionary.com)

Glee-off, which is what they called the mash-up competition between the guys and the girls in the Vitamin D episode, is probably only used specific to that situation and in Glee itself. Kurt's and Rachel's competition against each other in determining who gets to do the Defying Gravity solo is called a diva off and I focused on looking for dictionary entries on this instead and I couldn't find any even in Urban Dictionary. This has probably been newly coined, perhaps by Glee itself. I wonder whether it will catch on soon? And what if we coin our own terms like, oh I don't know...school-off? makan-off? haha. This is quite exciting. =)
