look up any word, like swoll:
 
1.
A disgustingly cute nickname for one's significant other, featured (perhaps coined) on the Seinfeld episode "The Soup Nazi." Often used in a tongue-in-cheek manner when one desires to imitate those publicly affectionate individuals one dreads encountering in a restaurant.

2.
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.
Despite being their eskimo kisses and entangled arms and legs, they denied being schmoopie.
