Gombeen is a derogatory term used in Irish slang to describe a greedy, conniving or unscrupulous person who is only interested in making a profit for themselves. There are many synonyms for this word, some more colorful than others, including chancer, spiv, wheeler-dealer, shark, profiteer, charlatan, swindler, racketeer, and extortionist. All of these terms imply a person who engages in unethical or dishonest behavior in order to gain money or advantage, often at the expense of others. Whether in business or in personal life, gombeens are often seen as manipulative and untrustworthy, giving rise to the need for these synonyms to express our disdain for their actions.
