Answer :
Final answer:
The term 'couch potato' is a metaphor signifying someone who is physically inactive and spends most of their time sitting, in this context, playing video games all day.
Explanation:
In the given sentences, the phrase 'I was a couch potato' is a metaphor. A metaphor is a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable. Here, the phrase 'couch potato' doesn't mean the person literally becomes a potato on a couch. Rather, it's a colloquial idiom that compares the person's behaviour - playing video games and eating chips all afternoon, not doing anything else - with the inactivity and laziness typically associated with a potato sitting (metaphorically) on a couch. Thus, it implies that they spent their time being very inactive physically, just like a potato that sits still.
