A proshipper is a term used in online fandom communities to describe someone who supports a specific romantic pairing or shipping in general. The term can also refer to someone who supports shipping that is deemed problematic, such as abusive dynamics, harmful age gaps, and incest, and believes in the freedom to create and consume fanworks with such elements. However, the definition of proshipper is not universally accepted, and there is some confusion around the term. The term "anti" is sometimes used to describe those who oppose the problematic tendencies of proshippers.
