My son said "freaking" this morning. I'm not using that as a euphemism for the real 'F' word. "Freaking" is actually what he said. I've been told that "freaking" is not a bad word. Wait until it comes out of your kid's mouth. It sounds pretty bad.
He was telling me about a video game. As a mother of two boys obsessed with video games, this is what I heard: I killed blah blah dragons blah. Fire arrows blah kill kill kill. Blah. Then he said, "I tried to kill the blah blah, and it was so freakingly hard."
Freakingly? He said freakingly. Of course he did. Because in that sentence, the word is used as an adverb, and freakingly would be correct.
