Today's Obamaism:

Barackefeller (buh-ROK-uh-fel-er) n. A hypothetical general-election ticket in which Barack Obama chooses West Virginia Sen. Jay Rockefeller as his running mate.

Example: Though a small faction of campaign aides argue that choosing the West Virginia senator as a running mate would tap the Rockefeller family's historic wealth and power, most senior advisers agree that the portmanteau word "Barackefeller" is both inevitable and prohibitively unpresidential.

Since Slate first launched its Encyclopedia Baracktannica in February, more than 800 readers have written in with their own Obamaisms, from "Barack Ness Monster" to "Post-Baracalyptic." The best of these entries, along with Slate's original Obama neologisms, are collected in a new book: Obamamania! The English Language, Barackafied, available now.

In conjunction with the publication of the book, we will be publishing a new Obamaism every morning and adding it to the Obamamania widget above, which you can add to your Facebook or MySpace profile or Web site.
