cutplug
n.— «The process is called “cutplug” herring, in which a knife is used to cut a beveled edge diagonally across the herring’s body. The “plug” is then attached to hooks so it will twirl at the end of the line in the artificial current created by the trolling boat.» —“The unkindest cut will scare away prey” Oregonian (Portland) July 24, 2006.
