It is an electronica song that uses sexual innuendo and has been compared to works of Ciara, Flo Rida, Petey Pablo, Britney Spears, and Gwen Stefani.

[1] Lead singer Nicole Scherzinger also contributed to the songwriting with coming up with the song's bridge; she took inspiration from Brandon Flowers of the Killers as she "wanted to make it a little bit more rock-y".

[5] Fraser McAlpine of BBC Radio 1 opined that rhythmically it borrows from Flo Rida's "Low" (2007), Ciara's "Goodies" (2004), and Petey Pablo's "Freek-A-Leek" (2003), but with the Pussycat Dolls' signature sensual sound.

[6] Lyrically, the song uses sexual innuendo with Scherzinger adopting "breathy vocals",[4] which were compared to Gwen Stefani by Yahoo Music's Jamie Gill.

[8] In March 2009, a two-track version was available for digital download in Australia,[9] while in Germany an extended play (EP) was released consisting of remixes of "Bottle Pop".

[10] New York Daily News critic Jim Farber wrote that "Bottle Pop" has "a moronic hook [listeners] can't resist".

[12] Nick Bond of MTV Australia and Levine of Digital Spy regarded the song as one of the musical highlights of Doll Domination,[6] with the former describing "pneumatic".

[13] Spence D. of IGN described the song as "insidious" adding "it's straight Mac 'n Cheese, ultimately not the most healthy choice, but kind of tasty nonetheless".

[15] Nic Oliver of musicOMH agreed with Derdeyn equating Dogg's contribution to someone who is sleepwalking, adding that the lyrics were written by a "sophomore student on a weekend bender".

[16] Rudy Klapper from Sputnikmusic deemed Dogg's guest spot as "one of the weaker ones of his career" adding "the track's lackluster chorus deflate[s] any energy he might have afforded them".

[31] The Pussycat Dolls first performed "Bottle Pop" during Dick Clark's New Year's Rockin' Eve with Ryan Seacrest '09 that was broadcast live by ABC on December 31, 2008.
