When you get drunk and high on weed, decided to jump some crazy gangsters, then get your ass kicked for being a total dumbshit. It also defines the limpness of your Mr. Dick after you take a cold shower (note: it is very hard to have sex with a wiggly jiggly) It also defines the state of your mind for being dumbshit enough to look up "wiggly jiggly" on a website.
