Background
The single comprises two songs, the title track "Oppa, Oppa" and ballad "First Love". "Oppa, Oppa", written and produced by frequent collaborators Youngsky and Peter of Korean R&B/hip-hop group One Way, is a track that features a "lively rhythm and beat in a retro dance atmosphere" with lyrics implying their group's popularity. The song also has a similar lyrical concept to the group's track with f(x), "Oops!", from the repackaged album A-Cha. It also contains an interpolation of the song "Funkytown" by Lipps Inc. "First Love" is a two-minute piano ballad written by Donghae which serves as a prelude to the title track.

The song was first performed at group's Super Show 4 Seoul concert on 19 November 2011. Then, a month after the performance, SM Entertainment announced that both Donghae and Eunhyuk will promote the song on music shows: Music Bank on 16 December, Music Core on 17 December and Inkigayo on 18 December.
