An excuse for people you barely know or like to invite you to spend a fortune on them and fawn over them for a whole day. Sometimes they will give you expensive wedding lists and yet get away with feeding you Asti Spumanti and mild cheese sandwiches.
Once invited to the wedding it is a downhill spiral into debt and having to buy summery dresses in the winter, and an expensive gift that you know that you cannot afford and that they will never use.
"so how come you can't afford that new BMW 3 series?"
" I have been invited to a wedding and have to save up for the gift"
