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".
"Max and all his gay friends were going to go to the bar, but he persuaded them to check out synergy fly fishing instead, and now they all spend a lot of time at the river"
"I went synergy fly fishing, and came home with several nice bass and a very sore asshole"
