"Down Bad" is about a newfound infatuation.^[1] In a track-by-track commentary for Amazon Music, Swift said that she wrote the song comparing "the idea of being love bombed, where someone rocks your world and dazzles you and then just kind of abandons you as an alien abduction where you were abducted by aliens".^[2] In the lyrics, Swift's character encounters a fleeting sensation that she describes as "cosmic love" and deeming her love interest "my twin".^[2] Musically, "Down Bad" is a synth-pop song^[3] with R&B inflictions, showcased via its dynamic shifts and cadences.^[4][5] Swift sings using syllabic syncopation^[6] over a subdued electronic production with a synth bassline.^[7][8] Chris Willman of Variety compared the production of "Down Bad" to Swift's 2022 album Midnights, pointing out the "sinuous groove, topped by a kind of distorted-electronic voice effect as its own instrumental track".^[9]

SLUG Magazine's Palak Jayswal dubbed "Down Bad" an "anthem that Swifties always crave", adding that it captures the essence of love bombing and falling for another person.^[16] Josh Kurp from Uproxx felt that the track was a representation of the album's verbose and genre-less quality but opined that it was "extremely personal [...] to the point of discomfort".^[17] John Wohlmacher of Beats Per Minute criticised Swift's excessive use of "metaphor-chains" in her lyricism which dilutes the emotional sentiment she wants to communicate.^[18]
