Meaty Thwack

The sound effect created in cinema and games when skin is violently struck with a blunt force object.

Notably found in the show Daredevil and the game Rust.

There was a beautiful, meaty thwack when I used my rock to tear the chicken breasts from the body of that hog.

Daredevil took down the muggers with a flurry of meaty thwacks, leaving them senseless on the ground.
