It's the snobbery, not the meaning.

I've been partial to the crypto community since the early 90s and there appear to be three popular ways to dismiss one's security work without bothering to understand any details -

  1. Quoting an item from the snakeoil markers list

       This is the most popular method. It has a good 
       mass appeal as it clearly implies that your 
       opponent is a complete idiot and puts him in a 
       position of needing to prove the opposite.

  2. Gutmann Sound Wave Therapy quote

       Whenever someone thinks that they can replace 
       SSL/SSH with something much better that they 
       designed this morning over coffee, their computer 
       speakers should generate some sort of penis-shaped 
       sound wave and plunge it repeatedly into their 
       skulls until they achieve enlightenment.

       This is as great, arrogant, includes a "penis" 
       and generally makes first-time impression. It
       can't be used too often unfortunately.

  3. Invoking Kerckhoffs's principle and alike

       This is a sophisticated way. Don't really need 
       to understand what the term is or if it applies 
       in a given case. The idea is to just dazzle the 
       opponent with obscure terminology to show they 
       don't know a shit about cryptography.

You've gotta try and be on a receiving end of these. An incredibly welcoming opening of a dialog between the peers. Thickens your skin like nothing else.
