Real Soon Now

Fannish term meaning “eventually” (as in "when I get around to it") used as hyperbole with initial caps – Real Soon Now – so frequently that it could also be rendered as the acronym RSN. There were also variants in common usage: “soon or Soon” was particularly popular in SAPS and at times it was sufficient to say “Soonest.”

Capitals denote sarcasm.

When the MSFS/DSFL was going to have: a convention, a decent fanzine, an active membership, a properly run meeting and many other fine things that didn't quite happen. Term created by Martin Alger in 1950 to describe the excitement evident in the voice of George H Young when he spoke of the con to be held in Detroit RSN.
