In Denmark, a traditional wedding custom consist of the groom disappearing at some point during the marriage celebration and the male guests all kiss the new bride. After the groom returns his bride eventually leaves the room and all of the female guests kiss him.
When Danish guests bang their fork and knife on their plate the bride and groom are to stand on top of their chairs and kiss. When guests stomp their feet the bride and groom are supposed to kiss under the table. Its all about kissing 🙂
