Couples who are constantly feeling the need to be touching, holding hands, kissing, and calling eachother pet names like shmoopy, as if they are forever caught in the state of being a brand new couple that is madly in love. It's from seinfeld
That is the shmoopiest couple I have ever seen. They are always eskimo kissing in front of everyone and it's awkward as hell.
1. Affectionate nickname for your significant other.
2. A couple who is overly cute and affectionate towards each other. They often display more than one of the following characteristics ad nauseam; head on others shoulder or lap, multiple smooches to the face, Eskimo kisses, rubbing or petting each other, embracing, coddling, whispering, staring longingly into each others eyes, cooing, hand-holding, and calling each other pet names such as schmoopie. They are often unaware of the disgust of those around them.
