fubar with postwar miracles

So the boy and his X-Box buddies have started using "PR0N" as a clan tag. I raised an eyebrow at it when it came up, but have pretty much left it alone because I figured if I made a big deal about it, he'd just keep it on there longer, because teenager. Sunday when his friend was over and they were playing on X-Box Live, someone asked what it meant. Much Beavis and Butthead-style giggling ensued.

"Yeah, buddy," says I, all sarcastical-like. "What does 'PR0N' mean?

More teen boy laughing. "Guys, my mom wants to know what it means..."

"Tell her it's Chinese!"

"Yeah, yeah - mom, it's Chinese. You wouldn't understand."

"Chinese, huh..." says I. "That's funny, because according to the internet, it means 'porn'"

"Uhhhhhh..."

"Look, I don't know how dumb you think I am, but let me assure you, I'm not that dumb."

Tell her it's Chinese...for Christ's sake...doesn't this kid know who I am?
