Police officers were confronted by a woman naked from the waist down when they were called to the lobby of some flats.
Selina Housley, 32, could hardly stand up and the officers could only do their best to cover her up, Anne Wroe, prosecuting, told Barnsley Magistrates' Court.
Housley, shouted, screamed and swore, Mrs Wroe said.
Mrs Wroe added: "People nearby seemed shocked and appalled about what happened. The defendant was wearing just a top. She was naked from the waist down.
"Officers did their best to make her decent but she was unsteady on her feet."
Jack Danaher, defending, said Housley had drank too much on a day off from work.
He said: "She recalls very little and is ashamed about what happened."
Housley, of Haverhill Grove, Wombwell, who admitted using threatening words and behaviour, was fined £36, ordered to pay £85 in costs and a £20 victim surcharge.
