I've heard in the Hassidic world, if two families decide that one's young fellow should meet the other's young lady, the couple has a brief, chaperoned, meeting, known as a b'shoh (spelling?), to determine if they're remotely compatible; if so, mazel tov, they're engaged. (Correct me if I'm mistaking my facts here.)
Is that a Yiddish word? Related to the Hebrew b'sha'ah, meaning for the time? Hungarian? Other?
