Some interesting words I’ve run across lately:

Wrapsimonious: “Joe recycles nothing, so when he carefully removes the paper from his gift, he’s just being wrapsimonious so he won’t have to purchase any.” (From Verbotomy)

Clickstream: The path taken through a web site.

Thinute: “A brief minute when I was two pounds thinner than usual.” (From Flawed Mom)

And two that sent me to the dictionary:

Crepuscular: Of twilight.

Gyre: I thought C.S. Lewis made this up in Jabberwocky (‘Twas brillig, and the slithy toves/Did gyre and gimble in the wabe), but it means whirl or gyrate.
