Snapedom

I understand what you're saying, as far as general discussion goes. And for a casual reader, who won't think twice about it, I can see referring to him as "Snape" simply because that's how he's named most of the time in the books. But anyone who starts to really look at the books and question the underlying assumptions--are things really as they are being presented to us?--is bound to start questioning the way in which almost all other characters in his generation get referred to fairly often (if not always) on a first-name basis, and Severus Snape alone is called "Snape." It just reinforces a sense of marginalization, distancing, contempt, and outsider status, a sense of disrespect, being seen as less than human, "not really a person," if you know what I mean.

Granted, that makes sense from the POV of the "Harry filter," but it doesn't make sense from the POV of fans and writers who view the character empathetically and/or sympathetically. It irks me enough in general discussion--maybe not to the point of being "truly obsessed," lol, but as the proverbial grain of sand in the shoe that annoys me whenever I encounter it. (Then again, I tend to be the kind of person who, once I notice something, wonders how long it's going to take the rest of the world to catch up with me and see a thing the way I'M seeing it. ;-)) But my point here is that is makes no sense, whatsoever, when someone is writing of Severus Snape in the context of an intimate relationship, to continue to refer to (and think of?) him as "Snape." By the time the clothes come off, most people are on a first-name basis!

Possible exception: Severus/Harry. I could see them continuing to call each other "Snape" and "Potter," though the subtext of those names would be rather different than during Harry's school years. And note that Snape/Potter is also parallel construction--but "Snarry," admittedly, has a nicer ring to it than "Snotter." ;-)

In general, I prefer just to use the full first names (or first-last/first-last) in naming a paring, rather than using the cutesy shorthand mashups. But I suppose I'm going against the grain, there, in a culture with J-Lo and Brangelina, et al. Not even Susan Boyle is safe, having been dubbed SuBo. Alas, what times we live in...
