unfunny

This term describes a failure of intent, where an attempt at humor results in a lack of amusement. It carries a sharper, more critical edge than simply saying something is not funny, as it implies a perceived effort to be witty that has failed miserably, often resulting in awkwardness or secondhand embarrassment.

In social contexts, calling a joke unfunny often suggests a critique of the speaker's taste or timing. It is frequently used in reviews of comedy performances or in interpersonal disputes to signal that a particular brand of humor is unwelcome or outdated.
