Heja BVB comes from the supporter culture of Borussia Dortmund, the German club founded in 1909 whose initials BVB stand for Ballspielverein Borussia. 'Heja' is a classic rallying cry, and the chant has long been sung by fans in the Westfalenstadion and shared online as a short audio clip. It spread through fan videos, soundboards and social posts rather than as a chart single, often paired with crowd cheering, and remains a quick identifier for Dortmund support during Bundesliga and European matches.
