The Yiddish phrase alta cocker is used to describe people of a certain age. Often, the Yiddish term is used in a derogatory manner. Alter coker means an old person, especially an old man.
I was startled to hear actor Micheal Douglas recently say alter cocker as he was promoting his new movie. He was describing the plot and his work with actress Diane Keaton who appears in the movie. Then, he said:
“This is a good movie for alter cockers!”
