SWALK

SWALK

1. An acronym for "sealed with a loving kiss," a phrase written on an envelope to indicate that one kissed it to show love for the recipient, perhaps literally and leaving behind a lipstick mark. You must have a secret admirer, because "SWALK" is written on the back of the envelope along with a red lipstick kiss mark.
2. By extension, written and sent with love and affection. This letter comes SWALK, since I can't be there to kiss you in person.
