One who frisks; a person who searches someone by patting their clothing, or someone who moves in a lively, playful manner.
From 'frisk' (to move about playfully or to search) plus the agent suffix '-er.' 'Frisk' itself derives from Middle Dutch 'frisk' meaning lively or brisk.
The verb 'frisk' entered police jargon as a euphemism for searching, but it originally just meant to move around energetically—language does that, turning playful words into procedural ones.
