The millennial whoop is a term coined by musician Patrick Metzger to define a musical sequence repeating the fifth and third notes in a major scale, which according to Metzger has been extensively used in 2010s pop music to create instant and easy recognition. Metzger described the term first in a blog entry on ThePatterning.com in August 2016, since then it has found widespread resonance in social and conventional media.
