The zaghrouta, also spelled zalghouta and called zaghareet in plural form, is a traditional form of ululation practised for centuries across Arab, Middle Eastern and North African cultures. Women perform it at weddings, births, graduations and other happy occasions to express joy and bless the moment, often in call and response groups. As short video platforms spread, recordings of the trill became a reusable celebration sound online, shared in congrats edits, family videos and memes where its unmistakable tone needs no translation to be understood as pure happiness.
