snaggy

A descriptive adjective with two main lives: in older UK dialect it meant bad-tempered or irritable — someone who snaps at people unprovoked. In its more physical, still-current sense, snaggy describes a surface covered in jagged protrusions, sharp snags, or rough edges that catch on clothing or skin. Think bramble-heavy hedgerows, splintered timber, or tangled fishing line. The word has a tactile quality that makes the physical sense feel immediate — you can almost feel the pull of a snaggy branch.

Covered in snags, or similar sharp projections.

(UK, dialect, archaic) Bad-tempered; crotchety.
