thwacked

thwacked is the condition your mind is left in after habitual drug use even after sobering up. a thwacked individual will behave differently than they would have if they had never consumed drugs, the most common being drug seeking behavior AKA fiending but also lack of common sense, decreased intuition, degraded performance, etc. opioid use disorder is a an example of a thwacked condition but ALL drugs (from weed to wellbutrin) have the potential to thwack you one way or another if you fail to moderate usage. the only treatment is time but in some cases prolonged drug use may leave you with permanent brain damage and you will be forever thwacked.

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.
