What is the dingbat cccccc festive?

Oh, dude, the term "dingbat" actually refers to a typographical ornament or symbol used in printing. And "cccccc festive" just sounds like someone mashed their keyboard while trying to type "festive." So, if you're asking about a festive dingbat, I'd say it's probably a jolly little symbol hanging out on a holiday card or something.
