What it means
A lock-in is when the pub's meant to be shut, but the landlord quietly keeps a few people in and carries on serving after hours. It's half privilege, half low-level mischief. Usually it's regulars, mates, and whoever's earned a nod. Bit illegal, bit iconic, and always the start of stories that sound dodgy in daylight.
Usage examples
"We nipped in for one, landlord locks the door, and suddenly it's a lock-in. Three pints later we're belting Oasis while someone raids the crisps behind the bar."
"The Friday night lock-in at the Crown and Anchor went on until half past three in the morning, the landlord pulled the curtains across the front window after eleven and produced a homemade ham-and-cheese platter that none of the regulars had been expecting."
"There was a memorable lock-in at the village pub after the rugby club won the regional final, half the team in muddy kit, three improvised speeches from the captain and a piano singalong that finished only when the dawn light started showing through the curtains."
"Thought we'd had last orders, then Dave slid the bolt and it turned into a proper lock-in with warm lager and somebody murdering Wonderwall by the fruit machine."
"Only meant to stay for one at the local, but the landlord kept the regulars in for a lock-in and next thing you know it's two in the morning and everyone's sharing peanuts like they're sacred treasure."
Where it comes from
In Britain, lock-in comes straight out of pub licensing days when serving hours were strict. Landlords would lock the doors after closing time, keep a chosen crowd inside, and carry on pouring pints off the books. The laws eased up later, but the phrase stuck because the whole thing had already become pub folklore.
