I keep coming across the word “muppet”, both in the conversation of undergraduates and on the internet. And it’s used in a pejorative sense; apparently, a muppet is something that it is a bad thing to be. This puzzles me, because a very large number of the muppets from the Muppet Show are clearly excellent things to be (though I wouldn’t want to be Professor Bunsen’s assistant Beaker). And from the variety of contexts in which I’ve come across the word, I can’t quite fix the meaning. It’s clearly not an abusive word, since people seem happy to call themselves muppets (e.g. “I’m being such a muppet”), but beyond that I’m not really sure. Any help gratefully consumed.
