My legal opinion is that, in certain locales, it's enough to get you arrested on a variety of minor charges. The DA or judge is almost certainly going to toss it as soon as they see it, but getting arrested is still annoying and can affect some employment. Getting things expunged is very likely, but that still takes time and money.

Best to go with the alternate suggestions and try and watch your mouth. You can train yourself to not swear even when startled. Not a bad idea in any case.
