'Cool for the Summer' is a 2015 pop single by Demi Lovato, released as the lead single from the album Confident, and its chorus hook about having your mind on someone's body became one of its most quoted lines. On TikTok, short snippets of the chorus have been reused for summer-themed edits, transitions and lip-syncs, where the flirty lyric does most of the storytelling in just a few seconds. Its seasonal title, instantly recognisable melody and confident tone keep it returning every summer, long after its original chart run.
