Fake wedding: A celebration for women who have concluded they don't want to/might not get married but don't want to miss out on their 'big day'. A response to the fact that most women only want to get married for a) the proposal (flattering) and b) the party (more undivided attention). An opportunity for ladies to spend a foolish amount of money on a dress they will wear once, a decent hairdo, a massive cake, flowers, a chauffer-driven entrance, a good time for all their loved ones and a photographer (to capture the 'blushing' hostess in as much glory as her middle-age can muster). Ideally combined with 40th birthday celebrations to encourage the co-operation of one's nearest and dearest, as opposed being branded an 'asshole'.
You're invited to attend my fedding this April. (You'd better be there as I'll be having a whale of a time, whether you are or not, and the pictures won't look as good if I'm alone.)
