In a work-related e-mail I got today, the subject read:
Obfuscation functionality in our software

This was the first time I've ever had to use www.dictionary.com to look up a word at work.

The definition of obfuscation:

1) confusion resulting from failure to understand
[Synonyms: bewilderment, puzzlement, befuddlement, mystification, bafflement, bemusement]

2) the activity of obscuring people's understanding, leaving them baffled or bewildered
[Synonym: mystification]

3) darkening or obscuring the sight of something

So I suppose I can say that this e-mail title obfuscated me enough to use a dictionary.
