It describes a situation where an individual or an organization benefits from two different sources for the same contribution. Some synonyms for double-dip include "exploit," "take advantage of," "game the system," and "milk." Other options also include "fleece," "swindle," "defraud," "scam," and "hoodwink." These terms are often used in situations where someone earns or receives more than what is reasonably expected or appropriate. Whatever the term used, double-dipping behavior is often frowned upon and considered as unfair or unethical.
