"Did It On'em" is a song by Trinidadian-born recording artist Nicki Minaj. It was written by Minaj with J. Ellington, Safaree Samuels, and Shondrae "Bangladesh" Crawford, who produced the track. The song served as the fourth single from her debut album, Pink Friday, in the United States.

The song has a distinct sound when compared to the rest of the tracks on the album, in that it contains a harder, "massive, ungainly" beat, reflecting her prior work on mixtapes. It also features hi-hats in "overdrive" and multiple synth patterns sounding as if a car-alarm siren was going off. Lyrically, Minaj delivers explicit phrases talking about winning over her competition.

"Did It On'em" reached number forty-nine on the US Billboard Hot 100, and reached #3 on the US R&B/Hip-Hop Songs and #4 on US Rap Songs charts. A music video was released for the track, featuring Minaj behind-the-scenes and performing on the I Am Still Music Tour.

T-Pain and Lil Wayne's collaboration album, "T-Wayne", released on May 18th, 2017, uses this beat on the song "Breathe".

"Did It On'em" is a hardcore hip hop and post-dubstep song that has instrumentally been described as having a massive, ungainly beat. Producer Bangladesh creates hi-hats that have been described as on overdrive. Multiple synths are heard on the track that have been described as blowing up like "a car-alarm siren." One of Minaj's more lyrically explicit songs, the lyrics speak of Minaj winning over her competition, in phrases such as saying she "shitted on 'em" or "pissed on 'em." Brad Wete of Entertainment Weekly said Minaj was "ordering her Barbies to put up two fingers if they’re crapping on their competition." Mark Hogan of Spin also reviewed the lyrics, commenting "she pulls out an imagined 'dick' and pisses on a washed-up rival."
