Requested by one of my intrepid commenters, I will post a few examples of irony.
A lot of the examples I have are along the lines of sarcasm and metaphor. "I could care less", or "blew me mind". I don't particularly include want to include things like puns or outright lies, although for certain people, those count as well.
It turns out I'm much better at spotting misuses of irony than I am actually creating some. It seems like as soon as I am able to sub-categorize the ironic statement, it no longer seems like a valid example.
