THIS was the ultimate walk of shame.
An underage party girl discovered that sleeping it off isn't always the answer after drunkenly passing out in the bathroom of a New York bar - and waking up Friday morning to find herself alone and locked inside the nightspot.
Therese Hipolito, who is under the US legal drinking age at just 20, could be heard shouting from behind the roll-down gate at the Boss Tweed's bar before police set her free at around 9.20 am local time.
"She was a little upset," a police source said. "She woke up, and she was in the bathroom."
The reveler had been tossing back drinks with a friend when she nodded off on the floor of the bar's rest room some time before workers closed up at 4am, sources said.
She woke up a few hours later, freaked out and called 911 at 7.55 a.m., according to cops.
Police officers sawed through a lock on the bar's graffiti-tagged gate to let her out.
Once free, Hipolito - still in a white party dress from the night before - shuffled into a cab and left.
Bartenders had failed to check the bathroom before closing up.
The bar may now be in hot water over the underage drinker, a police source said.
"They're going to have some issues now. We're really going to look into this deeply," one officer said.
Police have contacted the State Liquor Authority and were probing whether Hipolito had a fake ID, the source added.
The sloshed sleepover sounded like a nightmare to locals.
"I would think that they would clean the whole place at night before they close. It's terrifying," said Shirley Ye, a 21-year-old student who sometimes goes out in the neighborhood.
"I'd be terrified to wake up and you're inside a bar and it's dark. How could they have missed her?"
But it was just plain funny to Sweetina Kakar, a 26-year-old producer who lives nearby.
"That's one way to start your morning!" she said. "Do they not clean up their bathroom? Maybe we shouldn't be drinking there."
Boss Tweed's was formerly a dive with beer-pong tables and wild crowds every night but recently changed management and is now a swanky club.
Hipolito and Edward Doyle, who is listed as the bar's owner, couldn't be reached on Friday.
