A couple of rejects on the 2019 list really don’t seem like that big a deal. For example, if some guy wants to drive around with PLAYBOY on his bumper, can just the mention of that word be offensive or hurtful to someone? The officials had no specific explanation Thursday for that rejection. They said it may have already been entered into the DMV system in the past decade or so as part of an ever-growing list of banned combinations, and the computer could have rejected it based on that.
