Welcome to English in a Minute. A couch is for sitting and a potato is for eating. But
what is a couch potato? Dan, how is your new roommate? He's such a couch potato. He comes
home from work and watches weird shows all night. Well, it could be worse. Could it?
He watches Norwegian zombie films on very loud speakers. Sounds like this man needs
some headphones and maybe a new interest. A couch potato is someone who spends a lot
of time sitting and watching television. Be careful using this expression. It's like calling
someone lazy. It's not a good thing to be called a couch potato. And that's English in a Minute.
