Declan Nolan (24) shouted "n******" at passers-by as thousands of supporters thronged the city centre to celebrate.
He admitted public order offences, but failed to appear in court for the hearing of his case and had a bench warrant issued for his arrest.
Nolan, of Harcourt Street, pleaded guilty to public intoxication and breach of the peace by using threatening behaviour.
Dublin District Court heard the incident happened at Dame Street on September 1, 2012.
Garda Philip Earl said that he saw the accused in a "highly agitated state".
He was "shouting abuse and screaming 'f****** n******' at passers-by". Garda Earl explained that it was the night of the Notre Dame-Navy American football game and there were thousands of people in the Temple Bar area at the time.
The garda approached Nolan, and told him to calm down but he failed to comply with this direction.
He was eventually arrested and brought to Pearse Street Garda Station, where he gave his name and "various addresses and variations on his date of birth".
The garda found there was a warrant out for Nolan's arrest at the time and this was why he was giving varying details.
The court heard Nolan had 20 previous convictions and had been given a two-year suspended sentence in 2011 for burglary.
His criminal record also included convictions for assault causing harm.
Judge Michael Walsh issued a bench warrant for Nolan's arrest and sentencing.
