What does sleaziness mean?
Sleaziness is an informal noun for the quality of being sleazy. Its most common use describes conduct, organizations, or dealings that are disreputable, unscrupulous, cheap, or of poor quality, as when a newspaper describes a politician’s conduct as sleazy or consumers complain about a company’s sleazy practices. The word can also refer to physical dirtiness, neglect, or squalor, although this sense is less common. Sleaziness is more pointed than merely saying that something is bad: it suggests something shoddy, furtive, exploitative, or beneath proper standards. The term frequently appears in journalism and political criticism, where it conveys strong disapproval without necessarily making a specific legal accusation. Its familiar, somewhat dismissive tone makes it especially effective for conveying that a person or institution has behaved in a morally or materially unsound way.
