backspatter
Blood flying backward
Backspatter is the spray of blood, tissue, or other material that travels backward toward a source of impact—typically a gunshot wound.
The term belongs to forensic science, where analysts examine backspatter patterns to determine the position of a shooter or the nature of a wound: Backspatter on the defendant's sleeve placed him at close range.
