1. n. a person who collects two salaries; a federal employee who collects a federal pension and Social Security. The double-dippers say they weren’t doing anything wrong.
2. n. a person who dips a chip or veggie into a dip or sauce after having taken a bite of the chip or veggie, thus risking the introduction of germs into the dip. I always watch the snack table to make sure there are no double-dippers.
