the.com/laceration

A wound with jagged edges, because your body refuses to tear in a straight line.

means A deep, torn or ragged wound in the skin or flesh, caused by tearing rather than a clean cut.

from From Latin 'lacerare' — to tear to pieces, mangle, or rip apart — which also gave English 'lacerate.' The root is kin to 'lacer,' meaning torn or mangled. The same Latin stock may be distantly related to 'lacuna,' a gap or missing piece, which fits: a laceration is flesh with a ragged gap torn into it, not a tidy incision.

torn and ragged, not clean like a blade cut
cause
blunt force, not sharp objects, despite the drama
