The phrase indicates a collaborative dressing endeavor, where four individuals coordinate their attire for a Halloween celebration. This concept extends beyond individual costume selection, emphasizing a unified theme or visual representation achieved through the combined outfits of the group. An example includes four people dressing as elements of a deck of cards (King, Queen, Jack, Joker).
This type of costuming promotes camaraderie and shared creative expression. Its value lies in fostering teamwork and producing a more impactful visual statement than individual efforts alone. Historically, group costuming, though not always specifically for Halloween, has represented unity, satire, or performance art. The emphasis has shifted over time from purely practical or ritualistic purposes to entertainment and social bonding.
