Dince

This word is a made up "swear word" to be used by babysitters with kids, when they are not able to use actual foul language. Art of the usage depends in others reacting as if one said a very foul word. It is common in the southwest suburbs of Chicago and parts of Wisconsin, spreading likely from common families.

"Kids, start behaving. Stop being such a Dince "

"Oh my, the kids were such dinces today"
