Pre-slash

Pre-slash 

Refers to stories in which a homosexual romantic relationship does not yet exist, but there is the potential likelihood for one to occur as there is noticeable attraction or clear feelings between same sex characters. Such stories are still technically Gen and rarely exceed a PG-13 rating, but due to the non-heteronormative insinuations are often marked just in case. Alas, there is no opposite "pre-het" version, as heterosexual inclinations are generally considered expected and unworthy of separate mention in our current culture, much to some people's (ahem!) dissatisfaction.
