New Swear Word

As all good parents say to their child, "We don't swear." What do you do if your child creates their own swear word... and knows how to use it at times when a little !@# would be appropriate?? Drew has coined the word "aspen" for his own personal form of profanity. He uses it here and there, and will call his brothers "Aspen!" when he is mad. It really is quite funny, but perhaps it shouldn't be so.
