Bare-assed is an informal term used to describe someone who is stark naked. However, there are several synonyms that can also be employed in its place. These include words like nude, exposed, unclothed, stripped, naked, and unclad. Each of these terms can be used to describe someone who is completely without clothing. There are also more colloquial expressions like "in the buff" or "in the raw" that are often used in a humorous or playful way. Regardless of the terminology used, the meaning remains the same: someone who is "bare-assed" is showing off all their goods without any clothes to hide behind.
