What's that stink?

Discussion at the office this afternoon was: identify that funk.

Someone said "Does it smell like Sales Office's stinky cheese farts?"
Since we have a sewer problem and it is zero degrees today, I offered "Does it smell like the sewer is unthawing?"
"UN-Thawing? Did you just say un-thawing?"

Hoo-boy did I get knocked around for using unthawing. Much like irregardless it's apparently a pet peeve around here. Still, I wanted to prove my point that unthawing is as much a word as the non-standard and nonsensical irregardless. I looked up unthawing on Wikitionary where it's apparently just fine and informed them of the fact.

Scoffingly "Wikipedia, you may have as well looked it up on Urban Dictionary! Here look on Dictionary.com; it doesn't exist! It's not a word!"

Continuing to prove my point I did look it up on Urban Dictionary:

To freeze. Often used as a synonym for thaw or defreeze, although this is hideously incorrect. It actually means the opposite, when taken literally. Don't argue it. You are wrong.

Pete "The pizza was frozen so I let it unthaw for half an hour."
Willy "Get out of here you hick. And for the record, it's 'thaw'."

Don't argue it. You are wrong. I nearly pulled a stomach muscle I was laughing so hard and the guys were flouncing around going "don't argue it, YOU ARE WRONG! You hick!"
