Ironic Weather
Never heard of it. Oh yeah, I just came up with it. Ironic weather is when you look outside in the morning, to see if it's raining, which it isn't, so you get dressed and leave the building to feel a mist. So you go back upstairs and grab the umbrella and trenchcoat and proceed to walk to work. It never rains because you're prepared, which, btw, is Murphy's Law.
By the time you've walked all the way to work, you're wet from sweat. That's ironic weather.
Of course, if you're Chuck Norris, you're sweating bullets.
