Sobre este som
This is a five-second voice clip built around a single word stretched into a long, drawn-out 'niiiig' that keeps going well past a normal shout. The drawn-out delivery makes it feel funny and awkward in equal measure, like an over-the-top reaction that refuses to end and turns a simple call-out into a joke by itself.
