Common nickname for the Daily Mail - UK tabloid newspaper aimed at uptight Middle Class English people and generally disparaging towards women, especially celebrities. For example, frequently printing images of celebrities going about their daily lives, looking perfectly normal, and then criticising them for wearing trainers or not wearing make-up.
This phrase is much used on DigitalSpy forums.
I can't believe the Daily Misogynist are at it again! One article criticising working mothers and another slating Kim Wilde for going to the shops in jeans and trainers.
