This happened a couple weeks ago - I posted on my FB page - but thought I should share it here.
At work, one of my coworkers was talking about his XW. Telling one story after another culminating with the revelation that XW had stolen $65K dollars from their 19YO son immediately after he was in a major car accident. (Money was from insurance company.)
I looked up and said,
"So, your XW is a twatwaffle."
Coworker was just taking a drink of his pop - which he immediately snorted up his nose and sprayed across the table AT another coworker.
