This is a short spoken exclamation, about two seconds long, delivering the line 'what the f was that' in a blunt, startled tone. It lands as pure bewilderment, the kind of instant reaction to something odd, sudden or hard to believe. It works best as a quick burst of confusion that makes an unexpected moment feel funnier and more dramatic.
