A smooch is a big kiss, and to smooch is to kiss someone.

People express affection by kissing each other — so you may give your dog a smooch on the nose, or smooch your sister's cheek. You might, on the other hand, refuse to watch romantic comedies if you don't enjoy seeing the characters smooch. This informal word was a verb first, from the original smouch, which experts believe came from the sound of a great big smooch.
