A few interesting generations:

> You malformed garbage can of podagric pig precipitations

That alliteration for the second part is particularly pleasing. Although they wouldn't make good passphrases, it'd be fun to see an "oops! all alliterations" version of this.

> You misbegotten locker of pathological coon cat [dial] dross

I wonder how the "[dial]" slipped in there -- is it part of the animal list or the excrement list?

Edit: after refreshing a few more times I've seen a few other tags attached to other words ("labis [eccl]", "painter [S US]", "budget [dial]", "scrip [archaic]"). I'm guessing that "dial" means dialect, and the words that went into this were scraped from some old version of Roget's Thesaurus.
