Bleed as a term has arisen in and around the safety-techniques discussion of the past decade; I'm not sure who coined it or in what context. It concerns strong and possibly aversive or uncontrollable emotions that well up during play. If I'm not mistaken, at least sometimes it's identified as undesirable or unsafe.

Contrary to a lot of play culture right now, I'm not too invested in single-session, highly staged play. I don't mind the technique itself and have myself written some games along those lines, especially It Was a Mutual Decision, but there are so many of these at present, I find myself attracted mainly to "hey, we make up characters and play them for a long time," at least at the moment.
