The form of fishing where the line is used to propell the fly to the target. Unlike standard spin fishing where weight of the lure casts itself out, in fly fishing, the line propells the fly to the target because the line makes the tip of the rod bend, allowing the fly to reach its target in a well presentation. Unlike in spin fishing where most of the lures are made of wood, plastic, or metal, in fly fishing, the flies are made of synthetics, feathers, and other natural materials.

A type of sport, in which couples of mostly gay men take turns banging each other from behind while the other casts a lure into a body of water, and the first couple to catch a fish and cum at the same time gets to have their salads tossed by the other pairs of gay anglers. The sensation of simultaneously catching a fish while having a nut busted on one's ass results in a certain unique oneness with nature, or "synergy".
