Pasquinade

Meaning: a lampoon, satire or libel. Cotgrave:

The name of an Image, or Poste in Rome, whereon Libels and defamatorie Rimes are fastened, and fathered; also, as Pasquille.  A Pasquill; a Libell clapt on a Poste, or Image.

Usefulness: 2 (The reply-all email, the passive-agressive post-it, the anonymous online outburst, the aggrieved graffito; pasquinades all, and all potentially as comic.)

Logofascination: 1 (Derived from the nickname of a statue in Rome, on which such things were posted - for more on the statue, and the etymology of lampoon as a bonus, see here.)

In the wild: First encountered at LTA (see here for one in Latin) and then in the post linked to above, which mentioned Rabelais.

Bombinating

Meaning: buzzing

Usefulness: 1 (handy at work, even if you're not a beekeeper.  "That presentation was particularly bombinating, George." "Will this bombinating never end?" "I'm off sick - there is a terrible bombination in my ear.")

Logofascination: 1 (it probably shares a Latin root with bomb, and in its OED entry Rabelais gets the citation; it's in a Latin phrase in G&P and so the French text is cited rather than Sir Thomas' English one.)
