This is a short, 3.8-second voice clip of Eric Cartman blurting out his blunt two-word curse in a frustrated, fed-up tone. It lands as sudden, rude and funny, the kind of exasperated outburst that makes a bad moment feel smaller by saying it out loud. The line comes from South Park, where Cartman's impatient, self-centred temper often boils over into exactly this kind of outburst.
