“nuff said” punches my buttons. I have no idea why I react so strongly, but it riles me up every time.
The best I can describe my reaction is that this is a message board … there could be upwards of 100 posts in a thread, obviously it wasn’t “nuff said” because people keep on saying things. And many times it’s in a thread where including an explanation is the point. If someone is asking for TV recommendations, and someone comes in with “Buffy … 'nuff said!” it’s maddening that the poster couldn’t be bothered to add why he likes that show, or why he thinks it would be a good recommendation for the OP.
Oh yeah, and the idea that “nuff” is a good way of saying “enough” is annoying on its own.
