And you have to hold your hands up to indicate [square braces].

Or, if you're going for wiki-formatting, you somehow need to crook your hands & fingers into weird {{double-curly braces}}. Seems more painful than air-quotes...

Nope, you went one too far.

Make sure never to say anything like, "I was curious about X - what were some specific example?", though.

That might be too socially functional.
