stoppy back.....otherwise known as after hours. Extra illegal drinking time in a pub. This ancient tradition had waned over the last few years due to new more relaxed drinking laws in the UK, but still a few 'traditional' landlords keep the faith.
local...."Anychance of a stoppy back tonight boss?"
Landlord...."Aye, just let me get rid of a few strange faces first" (usually followed by a wink)
