Schmunktail is a word describing a state of being. When a person cannot sit without falling out of their chair, they are probably schmunktail. When a person sleeps with a member of the opposite sex who looks like he or she should be in a photo shoot for National Geographic, they are probably schmunktail. Simply put, schmunktail is oober-retarded-shit-housed drunk.
Caroline was so schmunktail, she felt out of her chair, and upon raising herself, kissed a man who looked like the love child of Liza Minelli and Joe Pesci.
