The new couple usually gets cutlery and crockery, pots and pans, all kinds of kitchen equipment, things for decorating their flat, bed and table linen, and gift vouchers.
The friends of the fiancé organise a stag night for him. It can be house party or they can book a room in a restaurant or pub. They drink and eat and enjoy themselves all night. A similar party, called a hen party, is organised by the friends of the fiancée where only women are present.
