Alaaf is the traditional greeting of Carnaval in the southern Netherlands, especially Limburg and North Brabant, and in the Rhineland carnival in Germany. It is shouted by revellers, princes of carnival and parade announcers throughout the season leading up to Lent, as a counterpart to Helau used in other regions. Short jingle versions like this one spread online as ready-made openers for party playlists, parade videos and seasonal greetings, which is why the shout remains instantly recognisable even outside carnival week.
