A term that applies to males that fail to follow basic sanitary hygiene after the act of urination. A male is a "Jiggling Jim” when he urinates, holds and shakes his member (some shake multiple times) then simply zips up and leaves the restroom failing to wash their hands. This is why you should always wash your hands because there may have been several “Jiggling Jims” before you.
