My girlfriend, her friends, and I were sitting around and chatting. Some of her friends fish. Some don't. Throughout the conversation, we would use fishing terms that they would not understand.
So I'm starting a thread with some fishing terms. Feel free to add. If the term is a local one, feel free to add that too. It could be helpful for those getting into the sport.
I'll start with four terms.
Walter - A large fish. It was the nickname that Henry Fonda's character, Norman, in On Golden Pond called a large trout that he was trying to catch on his homewaters.
Homie - A large wild fish. I learned this term from one of my guide buddies. The local river we fish is full of wild trout.
LDR - Long distance release. The fish releases itself a long distance away from the angler.
PMD - Pale Morning Dun mayfly.
