While sitting in a restaurant booth, you lazily dangle your wrist off the side of the table closest to the flowing stream of muff and occasionally and lightly jerk your dangling hand palm-side up in a hooking motion at the wrist. Discretion is the key as most muff will be keen on your intentions. With some luck and skill, you will be able to hook some quality muff!
Dude, I don't think the muff are biting today...
Did you bait your "muff hook"?
Imma gonna catch me a marlin!
