This is a really stupid Slang Term which is used to describe a person who is addicted to shopping. The use of the pseudo-suffix “-aholic” is an example of a rather un-intelligent use of language, as it is taken from the word “Alcoholic” – commonly used to refer to a person who is addicted to drinking alcohol.
However, this is also wrong. The word “Alcoholic” – by definition (and I don’t mean the one in the dictionaries), describes a person’s physical condition rather than that person’s addiction.
Have An Excellent Day!
