Pumped Up Kicks is a song by the American band Foster the People, first released in 2010 and widely popular in 2011. Its breezy indie pop sound and instantly recognizable whistle hook helped it spread across radio, YouTube and later short-form video platforms. Online, the track became a familiar choice for ironic meme edits because its relaxed mood clashes with awkward, unsettling or chaotic visuals. That contrast keeps it in circulation long after its original chart run.
