Def.: That moment when something (often but not always [long-]awaited; also something [surprisingly] positive) happens in fandom. This can apply to something happening in the fandom, as in something being released or announced; it can apply to something happening in fandom, as in in the canon’s continuity; this can apply to anything in between.
Usage: After eighteen months, tonight’s premiere of Mad Men caused everyone who is emotionally invested in it no small measure of fan relief; throughout the episode, and usually correlating with things said to/by my Joanie [Christina Hendricks], I had smaller personal bouts of fan relief as well.
