Christmoween 

A dark time when Americans over-indulge and gain weight. Begins when the first Halloween candy is placed on store shelves, and doesn't end until the last of the Christmas candy goes on 75% markdown.

(also spelled Chrismoween)

I can't believe it -- summer's not even over yet and the Halloween candy is already out. Christmoween comes earlier each year.

Chrismaween 

Christmas and Halloween themed decorations blended in a festive manner, a la "Nightmare Before Christmas."

The candy cane goes to the best Chrismaween costume on Oct 31st.

Christmasween

Christmasween: Where you can't wait for Christmas, but it's still Halloween or close to Halloween or even after.

It's like the Nightmare before Christman, only a more huge gap.

"Your already decorating for Christmas when it's near Halloween!?"
"Happy Christmasween!"
