A friendship between a male and female based only on the hope of getting with the other person. This type of relationship may include a series of break-ups and hook-ups. Usually only one of the friends is single. The hope must be mutal between both parties and neither friend acts on their feelings in a productive way. It is virtually the oppisite of friends with benefits and the comment "we're just friends" must be made by both parties almost daily.

Literally everyone, ever. Including the writer of this definition.
