The term "wally wacker" is synonymous of the terms: dick / cock / penis. The term is very popular in the mid-Atlantic region of the United States, especially West Virginia.

It may also be loosely related to the act of masturbation / "jacking off" where one wacks his wally.
I forgot to clean my wally wacker last night when taking a shower and was stuck smelling fish for the rest of the day.

Stress was abound and rather than hooking up with the lady, repulsive anymore, I went ahead and had a good and relaxing wally wacker.
