We call these belly kisses "zerberts" as coined by Bill Cosby on The Cosby Show. That's where I heard the word zerbert! I even googled zerbert and found a definition: It is described as the act of pressing one's lips on a soft area of another person's flesh, such as their facial cheek, and blowing, producing a noise similar to that created by flatulence. Unlike blowing a raspberry (which is meant as an insult and a sign of disrepect), a Zerbertt is considered a sign of respect and affection
Very interesting indeed! All I know is I give the occasional zerbert on the cheek or belly and now they are zerberting each other. Funny boys!
