Dislike in a Context

If there are a couple of words I don't like seeing or hearing.. D.U.H. is on the list but only when used in a certain contexts.

It's fine if it's said in a light-hearted manner or infrequently. But XXXXXXXXX if directed in the wrong way and u know it's a real meant-it way. I can't find a word to fill in the Xs but its just not being nice.

And I can't stand it when some guy exclaims some hokkien word. If they think it's cool... I beg to differ. In fact I think the f word is anytime better than that hokkien one.

What I've written so far is not in a pique of irritation though I'm currently pretty displeased with some party in a faraway land. The thot juz struck me.
