In Burmese its called "Falling into house prison." We monks are not involved so they cannot blame us if it doesn't work out as well as expected.
The tradition is for the newly weds to offer alms to the monks, who admonish them about mutual responsibilities, and give a blessing after the event, which is a secular arrangement. As far as I know, the parents "give away" the bride by pouring water over the joined hands of the young couple.
Wedding receptions are sometimes held in the Mahāsi Meditation Centre. After offering alms to the whole meditation centre community, they feed family, friends, and invited guests.
