A man with a hearing disability from Kendal, Cumbria, was arrested after saying 'pig' in sign language to a police officer, a court heard.
South Cumbria Magistrates Court was told that police were called to McDonalds on Stricklandgate after reports of a man 'causing difficulties'.
Linley Hassan, 25, of no fixed address, refused to leave the restaurant and became 'confrontational' with the police.
Peter Kelly, prosecuting, said: "He was making a sign that the officer, who understood sign language, knew to mean 'pig'."
In mitigation, John Batty said Hassan had had a volatile existence of late and had been going to great lengths to reduce his alcohol intake.
Hassan pleaded guilty to being drunk and disorderly. He was given a conditional discharge and ordered to pay a £15 victim surcharge and a £30 contribution towards court costs.
