LMAO - there are so many names for your spouse or girlfriend - other examples include
SWMBO - she who must be obeyed
DW - Darling wife
WAB - What a b***h

(only for when you are really fighting otherwise it will cause the fight)
and as in your instance :
SWMBI - she who must be ignored
and referred to as so many other synonyms such as
better half
ball and chain
old lady
i am sure theres plenty more
