About

Let's Pump It Up! refers to a series of videos remixing the K-pop group Loona's song "Why Not?" The chorus of the song features the lyric, "Whoa, whoa, whoa, whoa, whoa… Let's pump it up!" This section is often remixed in bait and switch videos where a character from a television show or movie repeats "Whoa" before the video cuts to the "Why Not?" chorus.

Origin

On October 19th, 2020, Loona released their song "Why Not?" (shown below, left).
