kenclarked

Cider which is 7.5% vol because of a penalty duty thought up by Chancellor Ken Clarke in the mid 1990s.

They've only got kenclarked Cider in that shop!

CKO

Short for Cider knockout, when someone falls asleep at an inconvenient time after drinking lots of Cider.

I was watching that TV series last night when I had a CKO, so I hope it's repeated soon!
