drolly

This adverb describes a specific type of humor that is dry, eccentric, or slightly offbeat. It suggests a sense of irony or whimsy rather than overt laughter or slapstick comedy. The tone is typically understated, often implying that the person is amused by something that others might find strange or confusing.

Because it is a relatively rare and sophisticated term, it is most commonly found in literary contexts or formal writing. In casual conversation, speakers are more likely to use phrases like "in a quirky way" or "dryly" to convey a similar meaning.
