Irony is not bleaching your hair blonde hair a few years ago in an effort to emulate Britney Spears. That's not irony, that's dementia.
Irony is posting this ...
Me: I have six weeks to lose weight for my college reunion.
Megan: You know what you should do? Date someone and then have them dump you.
... shortly after maniacally crowing with love for Meghan McCain because of her stance on weight and how unfair it is that women are still discriminated against for how much they weigh.
Irony, you see, is when someone does or says something that is totally at odds with expectations. Bleaching your hair to look like a teen idol when you are so clearly emotionally stuck at the age of 14 in professional and personal behavior means that emulating Britney Spears was, in fact, totally expected. Blogging about the need to lose weight when, just moments earlier, you lauded Meghan McCain for ordering some right-wing loon to "stop talking about my weight" is, therefore, ironic. And, you know, stupid. As always.
