A general term referring to the awareness of fall being in the air; also, an unspeakable association alluding to the fall / autumn season.
Similar to Americana in the way that one cherishes all things Halloween and of autumn. For example, seeing Halloween decorations in Dollar Stores and Wal-Mart in September, noticing the changing of leaves color, watching scary movies, going to Halloween parties, et cetera.
Unfortunately, Halloween(icana) is usually quickly overshadowed by the concentration of the unbelievably marketable and commercial Christmas.
Joe: Mark, summer isnt over yet...its only August 29th, why do you have Halloween decorations on your house already?
Mark: Fuck you man, Ive got a serious case of Halloweenicana!
A Halloweenaboo is a fagtard like Garren Benfield that is obsessed with the fucking Halloween horror movie franchise.
He is a little nerdy downtard so that moron eats this kinda shit up, cuz' he's a little dumbass thorn in my anus.
It's a play on the word Weeaboo if you didn't pick up the joke.
I was just minding my business playing with Gus until the downtard Garren joined and ruined our time playing games by saying how much he wanted to suck Jamie Lee Curtis' cock. Then I told everyone, Garren Included, that he is a mother hunching halloweenaboo which no one picked up that joke cuz' they're rarted.
A person who loves Halloween above all holidays. Halloween is their Christmas, Easter, Valentines and St.Patrick's day all-in-one. Of course this person probably dresses mostly in black, could be kinda scary themselves until you get to know them, makes cool props, decorates their yard and home like a haunted house and has no problem coming up with the most creative and original costumes ever to show up at a party.
(Definitely an interesting person to know in my humble opinion!!)
"My neighbor is a huge Halloweenie! His yard looks like Night of the Living Dead every October!"
