This 16-second vocal clip stretches the name Markus into a long, humming mmmmm that keeps going past the point you expect it to stop. It feels silly, awkward and oddly satisfying, like someone teasing a friend by refusing to finish saying their name. The drawn-out delivery makes it land as a playful reaction rather than a normal call-out.
