The single is an introspective regarding Lamar's family and social life, alcoholism, and the peer pressure which accompanies it amongst his friends. In the first verse, he remembers his grandfather's drinking and resulting death, and the reasons that led Lamar himself to drinking. The desire from the perspective of his peers, is the social pressure pressed upon him to "get a swimming pool full of liquor" and then "dive in it". At the second verse, Lamar, now drunk, is conversing with his own subconscious, which is attempting to warn him of "drown[ing] in some poison". By the final verse of the song, Lamar is accepting his fate that he believes he will "probably sleep and never ever wake up".
The extended album version of the track features an interlude and a skit that expands on the concept story of the album. Now drunk and eager to impress his peers, he thinks once more of the album's love interest, Sherane, before detailing a shoot-out between Lamar's friends and their gang rivals, in which his friend's brother is shot and killed. "Swimming Pools (Drank)" is the album's lead single and the follow-up to Lamar's debut single "The Recipe".
In its first week of release the song debuted at number 100 on the Billboard Hot 100 and remained within the chart for another week, but two weeks later re-entered the Hot 100 and climbed up each week, progressing from the top 90 to number 81, 71 and 61. In its tenth week, "Swimming Pools (Drank)" climbed up to number 55 and the following week entered the top 40 of the Hot 100 at number 32, moving up to 25 and peaking at number 17. On the UK Singles Chart the song entered at number 63, remaining in the top 100 for one week. The song is Lamar's second highest-charting solo single on the Billboard Hot 100 behind HUMBLE. which debuted at number 2 and peaked at number 1 (though his features on "Fuckin' Problems" and "Bad Blood" reached the top 10 in the United States) and on the UK Singles Chart.
The music video, directed by Jerome D, premiered August 3, 2012 on 106 & Park. A review by the magazineRolling Stone shared a summary of the video stating: "In his new video for 'Swimming Pools (Drank),' Kendrick Lamar defies gravity, floating and tumbling in suspended space as liquor bottles fly upwards and smash into the ceiling. The rapper gets introspective on a woozy beat, considering the highs and lows of alcohol consumption and the sense of confidence it bestows upon the drinker. Lamar spends most of the video rapping alone, but color-filtered shots of a booze-soaked rager poke through the more contemplative scenes."
The official remix featuring his Black Hippy cohorts – Ab-Soul, Jay Rock and Schoolboy Q – was included as a bonus track on the Target Deluxe edition of good kid, m.A.A.d city. On 14 March 2013 producer Dev Hynes uploaded a reinterpreted rendition of the track by English R&B group, Mutya Keisha Siobhan to his official SoundCloud page. The track, entitled 'Lay Down in Swimming Pools', features an interpolation of the original Lamar song. Hynes later commented saying "Just finished recording new music with Mutya, Keisha and Siobhan, And the girls felt like having a bit of fun at the end of the last session – enjoy!!"
