At a wedding a friend of mine attended in Japan, she saw the bride and groom feed each other a slice of cake. He was told by the MC that it was "first bite" (ファーストバイト), a commitment the bride and groom make to each other. I think the commitment is that the man provides for the woman, and that the woman cooks for the man.
Is "first bite" a genuine English term for this tradition, or is it wasei-eigo (English made in Japan)? Or, worse yet, not a real tradition!
I looked in onelook.com, but the only hit it got was for an album.
