I try to avoid it because it dilutes your actual point. They're filler words, that are sometimes used for actual emphasis, but mostly just said out of habit and really don't mean anything at all.
Besides, if you rarely swear, it makes it even more powerful when you actually fucking mean it.
When used sparingly, a concisely uttered tactical fuck can he used to lay waste to your enemies and their entire extended family.
But, like, if you fucking just use it all the fucking time to punctuate your words without any fucking rhyme or reason, people will just think you've got nothing to actually fucking say.
