A "schmeer" has several meanings, often relating to a spread or a mess, but can also be used more generally to mean 'the whole deal'. In the context of food, it's a generous spread of something soft, like cream cheese on a bagel. It also can refer to an intangible whole, the whole experience. It can also describe a smear or mess. Finally, it can be a euphemism for something negative or unpleasant. Imagine a bagel with a generous layer of cream cheese.
