Another addition to the KrautBlog aviary: Schnaps (one p!) should be known to English speakers—it's a generic term for any hard liquor; a Drossel is a thrush; and Schnapsdrossel is a colloquial moniker for a boozer. I do not know how the term originated, but it remains a fact, in Germany and elsewhere, that alcohol leads some people to song.*
*Addendum: I learned today (3/14/2012) that the Drossel in Schnapsdrossel has nothing to do with birds. It's an old name for "throat", which survives in modern German only in the verb erdrosseln (to strangle)—must have the same Germanic root as "throttle". So, a Schnapsdrossel is really a throat through which liquor flows freely.
