Kiss the Mistress
(To). To make a good hit, to shoot right into the eye of the target. In bowls, what we now call the Jack used to be called the “mistress,” and when one ball just touches another it is said “to kiss it.” To kiss the Mistress or Jack is to graze another bowl with your own.
“Rub on, and kiss the mistress.” —
