Kind of late but I would be Boo Spooka
Damned if I can think of anything, and it’s too late for this year.
But if anyone has a suggestion for next year…
tRick-or-Treat?
Put me down for next year - madrabbitmonster / madscientistrabbitwoman
I could also have been
anyblackrose
anydeadrose
anyTheDeadRise
or some such
OOOOH! I like “anyTheDeadRise!”
Thanks Marley this was fun!
It did work! It’s a Halloween miracle!
MegaBoo
Yeah, I did not think the quote function worked like that, but it looks like it did the trick. Anyway I think everyone’s usernames are now back to normal.
I supppose Irishzombie would work. Or Irishmonster.
Suburban Plankton Attack has a nice ring to it. (Band Name!)
purplehorseboo? Naw, sounds too much like purplehorsepoo.
Many thanks to Marley('s Ghost) and the other mods for indulging us. It was tons o’ silly fun! I chortled maniacally every time I saw my user name was Bride of Toucanstein.
I’m taking Heart of Dorkness’s suggestion and calling dibs on Toucannibal for next year.
Mine would be zombiesmarch4th.
Scary Chick, no doubt
OOOOOH! Excellent! I likes! 
How about “anycrone?” Too far a reach?
Perfect!
How about Irishdeadman?
Isquishedman
“Dead Irishman” would be more elegant, but I suppose you could just stick “dead” in front of anyone’s name and call it Halloween!
I love making up stuff like this. Too bad that, unlike digs and his doodles, I can’t get paid for it!
Ooh - “Dead Whisperer” - maybe next year!
Dendarii Demon, perhaps?
Next year I’ma be Bloody Blendervedder
