"Post to Be" is a song by American recording artists Omarion, Chris Brown, and Jhené Aiko from Omarion's fourth studio album, Sex Playlist (2014). The artists co-wrote the song alongside Ty Dolla Sign and DJ Mustard; the latter is also the producer. The track was released as the album's second single on November 11, 2014. Musically the song is a hip hop club track that is built over a clap-heavy West Coast production. The song contains a "bouncy" production and samples Chaka Demus & Pliers’ 1994 song "Murder She Wrote". The word "post" is a sensational spelling of the word "supposed."
An accompanying music video was filmed in Los Angeles and was co-directed by Omarion along with Jay Ahn and Taz. The video premiered on February 17, 2015 and depicts the three musicians dancing on an all white backdrop.
Omarion sent the song to Aiko asking if she would make an appearance on the track; Aiko agreed due to her friendship with Omarion and began "playing with the rhyme scheme". While writing with longtime collaborator Micah Powell, the lyric "Post To Be" reminded Aiko of rapper Kevin Gates, and she told Powell; 'Whatever we say, I really want to say something about eating the booty.' He keeps saying in the Vines—'You ’posed to eat the booty.'" Prior to the release of the song, Omarion released snippets. The song was later leaked on November 11, 2014 by the LA Leakers. The song was released as the album's second single on November 11, 2014, through Maybach Music Group and Atlantic Records.
On January 22, 2015, Omarion revealed via his official Instagram account that he was filming the song's accompanying video in Los Angeles. Via the Instagram account Omarion posted photos of himself, Brown, and Aiko alongside a white Ferrari and standing on set by an all-white backdrop. On February 16, 2015 Omarion posted two clips of the video on instagram along with a caption saying "It’s coming…. #Posttobevideo", the clips depicted the three singers performing synchronized moves on an all-white set. The video was co-directed by Omarion along with Jay Ahn and Taz, and was released the following day on February 17, 2015. The video featured Omarion moon walking in front of a white Ferrari, accompanied by Brown dancing.
Naomi Zeichner of The Fader praised the video comparing it to a home abs workout stating it "is four pure minutes of perfectly crisp mirror-dancing that doubles as a home abs workout." As of July 2019, this video has over 690 million views.
