Party Animal

A party is a gathering of people who have been invited by a host for the purposes of socializing, conversation, or recreation. A party will typically feature food and beverages, and often music and dancing as well.

Some parties are held in honor of a specific person, day, or event. Parties of this kind are often called celebrations.

A party is not necessarily a private occasion. Public parties are sometimes held in pubs and bars, and people attending such parties may be charged an admission fee by the host.
