I like to make up new words, nonsense words. It amuses me.
A few years ago I started using the word "cobbist" to identify a person who likes to play the blame game.
It's derived from the acryonym COB - in turn derived from the phrase "culture of blame", which is my own bastardisation of the common phrase"blame culture".
My wife uses the phrase "cobbist" unconsciously all the time, because she likes it. Several of her workmates think it's real, and now use it in general conversation. People must look at them strangely.
My work here is done.
