Claus-strophobia
The feeling of being trapped and encroached on by Christmas; being unable to avoid or escape the commercials, the music, and the rest of the havoc that is wreaked upon all of us regardless of our religious denomination from Thanksgiving to new years'.
It's still a few days from Christmas, but I am dealing with a severe case of Claus-strophobia after going by the mall. Wake me up when it's over.
