'sleazebag' originates from the English word 'sleaze,' which refers to something sordid or disreputable, combined with 'bag,' a colloquial term for a person.

'sleaze' evolved from the German word 'Schlaz,' meaning 'ragged clothing,' and 'bag' has been used in English since the 13th century to refer to a container, later colloquially referring to people.

Initially, 'sleaze' referred to low-quality fabric, but over time it evolved to describe disreputable behavior, leading to the modern meaning of 'sleazebag' as a morally questionable person.
