Plural of grouch; people who are habitually bad-tempered and complaining, or instances of complaining.
From grouch (1900s American slang), possibly from Yiddish 'grushe.' Can be a noun (a grouch = a grumpy person) or verb (to grouch = to complain).
Oscar the Grouch made 'grouch' famous, but the word actually comes from Yiddish-speaking immigrants to New York—Sesame Street accidentally made Yiddish slang into American culture!
