Ruby Thomas, 18, was found guilty of the manslaughter of 62-year-old Ian Baynham, who died 18 days after the drink-fuelled assault in London's Trafalgar Square.
Police later found his blood smeared on her handbag and the ballet pumps she was wearing as she kicked him.
The court heard she smiled as she ''put the boot into'' Mr Baynham after he was knocked to the ground by another teenager, Joel Alexander ...
A third defendant, 18-year-old Rachael Burke, of Upper Norwood, south east London, was found guilty of affray at an earlier trial.
All three will be sentenced on January 26. Thomas and Alexander were remanded in custody after Judge Richard Hawkins refused to continue their bail applications by their barristers ...
Thomas, a former pupil at the £12,000-a-year Sydenham High School for Girls, had a previous record for violence.
She was just 15 when she assaulted a bus driver in Northumberland Avenue in December 2007, a short walk from where the attack on Mr Baynham took place.
On that night in September last year she was said to have been "off her face", acting in a "lairy, mouthy" way, and flirting with random men.
The court heard that Thomas screamed "f****** faggots" at the victim and his friend Philip Brown.
When Mr Baynham confronted her, there was a scuffle during which she hit him with her handbag and he grabbed it.
Alexander then ran up and knocked him to the ground, causing a severe brain injury as his head struck the pavement.
Brian Altman QC, prosecuting, said: "That did not suffice. There is evidence that the female defendants then began putting the boot into Mr Baynham, who was still prone on his back, clearly unconscious and in distress."
He said the girls were "fuelled by copious amounts of alcohol" and one witness likened the attack to a scene from the film A Clockwork Orange.
"Shocked onlookers saw repeated stamping to his chest and forceful kicks to his head," said Mr Altman.
Mr Baynham was in the first week of a new job as a team leader in border control working for Serco, which was contracted to the Home Office, when he was killed.
He had previously held a number of managerial positions in local government.
The day before the attack, he had phoned his sister Jenny Baynham and told her how much he was enjoying his new role.
She was at his bedside when he died from a brain injury sustained during the assault, together with Mr Baynham's friend George Richardson.
Mr Richardson described the victim as "a perfectly normal man who just happened to be gay".
The court heard that the teenagers who attacked him had been drinking before they set upon him outside South Africa House on September 25 last year.
When Mr Baynham and Mr Brown appeared, Thomas began making homophobic comments.
A scuffle broke out and Alexander, who had been with Thomas's group, ran up and punched the victim to the ground.
Mr Brown said his friend "fell like a corpse", hitting his head on the pavement with a "crunching noise". Blood was pouring from his head.
One witness saw Thomas stamp on his stomach and kick him in the head while saying "dickhead" and "f*** you" while another noticed that she was smiling.
The attackers ran off. In a Facebook chat the next day, Thomas joked about her row with "some c***" who pulled her bag, adding: "Ha, ha, ha."
