ass sucker

A vulgar insult used to describe someone who is excessively subservient, sycophantic, or obsequious — typically toward a person in authority. Synonymous with 'brown-noser' or 'ass-kisser' in meaning, though more sexually crude in phrasing. Typically used to express contempt for someone perceived as ingratiating themselves for personal gain. Common in workplace grumbling and schoolyard insults. The term can also be used as a general-purpose vulgar insult independent of its literal meaning.

A derogatory vulgar slang term for a subservient, obsequious person, someone who engages in figurative ass-sucking by fawning over those in power to curry favor. Closely related to ass-kisser but with a slightly more visceral edge. Used to dismiss people seen as sycophantic or spineless. The insult prioritizes contempt for servility over any literal anatomical meaning. The sucker element adds connotations of both weakness and victimhood, implying the person is being exploited by their own servility even as they perform it.
