n.a humorous coined variation of the
phrase darken one's door, meaning to appear in a doorway or at someone's
home as a visitor, especially when unwelcome due to annoying or offending the occupants. This
phrase is usually used in
negative contexts with the words never and
don't. Darken here refers to casting one's
shadow across a threshold. Although dating back to at least the 1700s, the
phrase is associated with
Victorian melodrama, where a young woman or
man is thrown out of a parental
home for some sinful
deed. A portal is a door, gate, or entrance, particularly one of
imposing appearance, such as to a palace.
