AntiSpam Linguistics

I was signing into a website and, for security reasons, was asked to type exactly what was in the highlighted box. It's usually something arcane like "okDec UR" and if you don't bold that one letter, you can't get in.

The symbols usually don't mean anything. But today ... wow, today's was a mindbender:

mesons). datedBra

[Note the bold, then the deformed emoticon, followed by the lingerie reference.]

I know these are never supposed to actually mean anything, but this one got me thinking the entire day.
