We all know that people misuse the the term 'irony' on the internet and in daily conversation.
What I'm trying to remember (having a bit of a brain fart at the moment) is what it is that people actually mean when they usually say something is 'ironic'. For a while I thought maybe 'piquant' but I dunno. Seems they've both been a bit misappropriated as blanket terms for just about any circumstance or event that seems mildly curious, interesting or coincidental with another.
The most common misappropriation of the word irony I've noted is it's use to sub for something like 'coincidence' or 'bad luck'. See Alanis Morrisette's 'Ironic' for an example.
The biggest irony about irony is that not everyone understands irony!
