If I recall this is from an anime movie called “Your Name” where what she is doing is making Kuchikamizake “alcohol” in her mouth Using her own saliva and than lets it pour out her mouth naturally into the small box “cup”.
It is made as an ancient tradition that not many people still do.
I do suggest watching the anime it is a body switching anime.
