This is an extremely short voice clip, just a fraction of a second, with a flat computer-style voice saying 'je mama'. It feels abrupt and silly, like a cut-off comeback that ends before anyone can answer. The humour comes from how tiny and deadpan it is, turning a throwaway phrase into a quick awkward punch.
