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.
Originally coined by two teenagers after they decided they needed to make up a word that accurately described them, Shmopsie is the epitome of awesome. Shmospie represents everything that is awesome, stellar, outstanding, cool, and fantastic and surpasses all of those things in every way.
