I try hard to avoid the ones mentioned in the article, but I'm sure I occasionally slip now and again. A lot of times it tends to be a matter of habit, and many of us are often unaware we use them.

The one that stands out most to me is the use of "'nuff said" and, although it may not be meant that way, I find it sounds like the poster, who utters this phrase, appears to feel that the discussion need not go any further, and their word/opinion/advice is the final one.

Thankfully, it appears no one takes them seriously, and discussions always manage to carry on.
