A bullet hit squib or a blood squib is a practical, pyrotechnic special effect device used in the film industry, theatre productions and first responder moulage training to simulate a bullet wound spurting blood. Typically, the effect is carried out with clothing instead of on bare skin in order to conceal the device. Even if the portrayal is not necessarily accurate or is exaggerated compared to real-life (in the example of the main figure, blood spews out of a thick coat while emitting smoke), filmmakers and the audience have become accustomed to associating this aesthetic with a gunshot wound.
