When I courted the young lady who became my seventh wife (or was it the eighth?), I whispered, sweetly, de omnino nihilo in her ear. Latin has some sort of odd effect on the opposite sex, somewhat like Morticia's use of French arousing Gomez on the old Addams Family TV show. Somewhat. Try it on your SO:

  • in hoc signo vinces
  • esse quam videri
  • dulce decorum est pro patria mori
  • ars longa vita brevis

    And my personal fave, sed qui fecit, refecit.
