Welcome to the Party was released in 2018 as part of the Deadpool 2 soundtrack, performed by Diplo, French Montana and Lil Pump featuring Zhavia Ward. The track was built as a high-energy party anthem for the film, and its short, confident hook made it easy to lift into brief video clips. Creators began using the opening as a shorthand for arrivals, celebrations and over-the-top entrances, and that simple association has kept it in rotation long after the film's release, especially in party montages and hype edits.
