The court heard a friend had told McCarthy he might be allowed into the party at the club, known as The Cabbage Patch, and became agitated when he was denied entry.
McCarthy, of Stile Acres, Lawrence Weston, was ordered to remain indoors under curfew for 10 weeks and pay his victim Edwin Williams £200 compensation and £100 costs.
Neil Treharne, prosecuting, said McCarthy became abusive towards door staff during the row at the club on May 7.
The court was told McCarthy accepted biting Mr Williams, who had his fingers in McCarthy's mouth in a "fish hook" hold as the doormen tried to eject him from the building.
A statement from McCarthy, read to the court, said: "I accept I acted recklessly and in a threatening manner. I was swinging my fists due to the number of people on top of me, but not with the intention of making a connection with any individual within the group."
McCarthy told police Mr Williams had tried to choke him by putting his fingers in his mouth.
Mr Williams was treated in hospital after the attack to prevent him contracting an infection from the bite wound.
McCarthy had been due to stand trial but yesterday admitted assault occasioning actual bodily harm and using threatening behaviour. Two common assault charges were withdrawn by the Crown Prosecution Service.
Mr Treharne said McCarthy had 36 offences to his name and was convicted of causing actual bodily harm in 2006.
John Stokes, defending, said McCarthy had been to his grandmother's funeral before going to the club and had been in a "poor emotional state".
He said the doormen were physically and verbally abusive to McCarthy and had tried to frog-march him along a corridor and out of the venue.
He said: "Mr Williams' hands went into his mouth. Mr McCarthy bit his finger and swung his fists, which came into contact with his cousin and another man."
McCarthy claims incapacity benefit for a broken leg.
