Founded by Daniel Dennett, the Philosophical Lexicon converts philosophers’ surnames into useful words (with often pointed definitions):

• bergson, n. A mountain of sound, a “buzzing, blooming confusion.”
• braithwaite, n. The interval of time between two books. “His second book followed his first after a long braithwaite.”
• chomsky, adj. Said of a theory that draws extravagant metaphysical implications from scientifically established facts.
• derrida, n. A sequence of signs that fails to signify anything beyond itself. From a old French nonsense refrain: “Hey nonny derrida, nonny nonny derrida falala.”
• foucault, n. A howler, an insane mistake. “I’m afraid I’ve committed an egregious foucault.”
• heidegger, n. A ponderous device for boring through thick layers of substance. “It’s buried so deep we’ll have to use a heidegger.”
• hughmellorate, v. To humiliate at a seminar.
• kripke, adj. Not understood, but considered brilliant. “I hate to admit it, but I found his remarks quite kripke.”
• rand, n. An angry tirade occasioned by mistaking philosophical disagreement for a personal attack and/or evidence of unspeakable moral corruption.
• turing, v. To travel from one point to another in simple, discrete steps, without actually knowing where one is going, or why.
• voltaire, n. A unit of enlightenment.

And, inevitably, dennett: “To while away the hours defining surnames.”
