Eric Wareheim of comedy team Tim & Eric directed the song's music video. It depicts three young women in an apartment listening to seapunk music and taking pictures on their phones when a flying giant lands next to their apartment and inflates their buttocks. The girls start to dance with their new butts after the walls of the apartment fall off and reveal a dancefloor. Major Lazer played the song several times in their shows and in music festivals; they performed with 2 Chainz at Coachella, at Rock Werchter in 2013, and at the Roskilde Festival in 2014. The song was included in Major Lazer Essentials (2018), their first greatest hits compilation.
