Chelsea captain John Terry told a court he was angry and upset at being accused of racism by QPR defender Anton Ferdinand.
Terry told the court he was abused "more or less every game" about an alleged affair he had with a former teammate's girlfriend. He said he would generally laugh it off.
Terry, 31, has been charged with a racially aggravated public offence for allegedly making an offensive comment to Ferdinand, 27, when their two teams played at Loftus Road in October. Terry denies the accusations.
Terry told Westminster magistrates' court that he was merely repeating the words "f*****g black c**t" to Ferdinand. Terry said: ''I thought he was accusing me of calling him a black c**t.
''I was very angry and I was upset.''
The exchange erupted on the pitch after Ferdinand taunted Terry about an alleged affair with former teammate Wayne Bridge's ex-girlfriend, the court heard.
"It's part and parcel of the game. You just get on with the game," Terry said of the abuse he received.
Earlier, his lawyers asked for the case against him to be dismissed citing lack of evidence and the reliability of Ferdinand as a witness.
George Carter-Stephenson argued the case was "so weak and tenuous it does not warrant it going any further".
The appeal was rejected by chief magistrate Howard Riddle who said Terry did have a case to answer.
Earlier, the court was played an interview between FA investigator Jennifer Kennedy and Terry carried out a week after the game.
During the interview, Terry said: "I have been called a lot of things in my football career on and off the pitch, but being called a racist I am not prepared to take.
"That's why I came out and made my statement immediately.
"I am not having Anton thinking that about me or anyone else. That's not my character at all."
The court heard how Terry's involvement with former Chelsea players Marcel Desailly and Didier Drogba African charities proves he was not a racist.
''My commitment to the projects demonstrates I'm not racist,'' Terry told police.
Terry faces a maximum fine of £2,500 if found guilty.
