Two good new (to me) turns of speech:

• onageristic analysis – an onager, as many of you already know, is a wild ass (and a type of siege engine – stop trying for extra points!). Analyses go hand in hand with predictions. What we have here is a dress-up name for a SWAG. Via an Aruba Networks training session.
• Lex Murphiae. Anything this ancient and constant should be rendered in Latin. Via Geoffrey Chaucer.
