(umlaut) I cannot possibly pick out one word. I love them all. When my kids were young teens and grumpy, and I wanted to take a picture, I used to pick words that they weren’t expecting. For example, I’d say, “Say penis.” That did it.
Their favorite word for a while was *limacine.”
@Tupara: I would use *callipygian.”
My favorite group of words are “Your mammogram came back fine.”
My least favorite words are definitely, suck and platypus.
