floss
v.— «Some anglers “floss” their fish, which is letting your line drift across a salmon’s open mouth and then setting the hook. The hook ends up just outside or inside the salmon’s mouth. Flossing is just another word for snagging, but it’s hard to prove an illegal act in a court of law, as the fish often gets hooked in a legal area, Thiesfeld said.» —“A lesson in combat fishing” by Chester Allen in Skokomish River The Olympian (Wash.)
