Wolf was released by South Korean group EXO in 2013 as the title track of their album XOXO, built around a wolf concept with dramatic choreography and animal-inspired vocals. The short howling hook became one of its most recognisable moments, shared by fans in dance covers, reaction clips and short-form edits long after the promotion period ended. Because the sound is instantly tied to EXO and to wolf imagery, it still works as a quick shorthand for wild energy, transformation and playful menace in fan-made videos today.
