   • 2007 June 23, Norm Zeigler, “The Low-Profile Westport River Offers a High Yield of Fish”, in New York Times‎:

     Chris used a spinning rod with a green-and-white bucktail jig while I cast a chartreuse Angel Hair and white-bucktail Clouser minnow with my 8-weight fly rod.

2. The end of a rivet opposite the factory head, which in a solid rivet may be bucked by holding a heavy bucking bar or similar-purposed tool against it, while the factory head is hammered until the bucktail is upset into an appropriate shape, most commonly pancake-shaped; the mandrel of a blind rivet generally upsets the bucktail into a doughnut-shape when it is pulled.
