Due to the extreme frequent usage of potty language around here, we have instituted a "three strikes and you're out" policy for any such words. We have actually seen an improvement and hear far fewer of these oh-so-pleasant words that our boys like to punctuate with.
But one of our savvier boys came up with this, a way to circumvent that silly rule:
"HEY! You're a big piece of strike word!!"
This same boy has also been known to sing the popular refrain from Gangnam Style as:
"Hey, bad word lady! Woo! Woo woo woo woo!"
