...Crap, I was wrong again!
Noodling is fishing for catfish using one's bare hands, and is practiced primarily in the southern United States. The noodler places their hand inside a discovered catfish hole. Many other names are used in different regions for the same activity.
The term "noodling", although today used primarily towards the capture of flathead catfish, can and has been applied to all hand fishing methods, regardless of the method or species of fish sought. The origin of the term is unknown.[1] Noodling as a term has also been applied to various unconventional methods of fishing, such as any which do not use bait, rod and reel, speargun, etc., but this usage is much less common. The term has also been applied to the similar capture of snapping turtles.[2]
