Edit: American English, I should say. The Brits have "bloody".
There’s some neat work on where within the original word you can add them, made all the funnier by hearing people dispassionately dropping strings of f-bombs “to see what works”.

Lazy profanity, which also has low value, is the form where the majority of the value of the expression is carried by profane words.
The not-lazy form, which has considerably higher value, is the form where profanity augments the primary value contained in the non profane elements of the expression.
In my view, the not-lazy form is to be respected and preserved. Using the lazy form is most generally a disservice to the speaker, though not always. Context remains king!
The absolute best are the ones in every languages that are so versatile. Like "fuck". One of these can replace whole sentences and still be as expressive.
