AFTER PARTY after party is a gathering that occurs after a party, a music concert, a premiere or the closure of a nightclub. An afterparty may provide additional social opportunities for people who do not want to return to their respective homes.The main purpose of the afterparty is to provide a relaxing environment, as compared t...o the earlier venue, where the atmosphere is usually more frenetic. During an afterparty people often sit down, relax, and chat freely, meet new people in a more controlled setting. If the original party was one that continued until late at night, the afterparty will often include a morning snack, which usually counts as breakfast. To be invited to the afterparty is very often considered a high honor. However, many people who are not invited to afterparties consider invitees to be elitist (i.e. the notion that only the beautiful people are invited to the afterparty).
