Rapper Dappy sparked a "mob attack" at a petrol station when he spat at two young women who refused to get into a car with him, his trial has heard.
Prosecutor Brian Stork said the 25-year-old, whose real name is Costadinos Contostavlos, pulled up in a car at a Shell garage in Guildford, Surrey, at about 3.30am on February 28 last year.
Mr Stork said Dappy and his friend Kalonji Stewart got out of the car along with a third man.
While Stewart went inside the shop Dappy began talking to Grace Cochran and Serena Burton, who were in a group sitting on the kerb outside.
Mr Stork alleged that Dappy tried to persuade the pair to come with them in their car.
When they refused he called the women "sluts", said one was ugly and then spat at them, but missed, the prosecutor said.
A man who just met the women, David Jenkins, stood up to defend them, and Dappy is said to have spat at him and it made contact before swinging a punch at him.
Tests on a saliva stain on Mr Jenkins' t-shirt showed a DNA link to Dappy, Mr Stork said.
Mr Stork told Guildford Crown Court: "It all kicked off."
He said Dappy was then joined by two other men, Kieran Vassell and Alfred Miller, who had arrived in a second Mercedes car with other unidentified men.
Mr Stork showed the jury CCTV footage, lasting just moments, from the garage.
It showed the men attacking Mr Jenkins and his two other friends, resulting in Mr Jenkins' teeth being damaged and a fractured nose to another man. They then all got into cars and drove off.
Miller and Vassell are alleged to have used their feet and fists in the attack, and Dappy is alleged to have got involved when he was released from a head lock.
Stewart also got involved, but less so, the prosecution claims.
Dappy denies two counts of common assault on the two women, one of assault by beating, of Mr Jenkins, and one of affray.
Vassell, 25, of Hammersmith, west London, and Stewart, 32, of Harborne, Birmingham, are each charged with affray.
Miller, 28, of Brentford, west London, has pleaded guilty to affray and his case was adjourned for sentence at the end of the trial.
