Detaching and reflecting is a good practice, especially where swearing is a verbal crutch for yet-to-be-refined thoughts. Give it a moment, dispassionately and accurately frame the thought. In the end, what you say will be much more direct, and far more useful to everybody involved.

Also consider swears like farts in a relationship. A well-chosen place and time, dropping one is hilarious. All the time though, you just stink.
