No, fishing is an art.

Flossing is snagging....you just do it in the mouth.

I have seen visible coho, king, steelhead and chum all come up and take a jig out from under a bobber into their mouth ON PURPOSE.

Maybe they were just mad at it, but SKILLED angler should be able to LURE the fish into biting his/her bait ON PURPOSE.

Intentional Flossing = Snagging
