Your mother's heart, dear, will mend with the advent of children, and her father's father, a wobbly kibitzer pointing to Kat's mom and muttering, A beautiful strawberry girl, why all the fuss, why all the disunion over a strawberry girl?

Bronzini looked on, sitting in when someone left but otherwise a kibitzer, unmeddlesome, content to savor the company and try the wine, sometimes good, sometimes overfermented, better used to spike a salad.
-- Richard Russo, Underworld
Kibitzer entered English first in America in the 1920s. It comes from the Yiddish word kibetsn (equivalent to German kiebitzen) meaning "to look on at cards."
