Can you guess the meaning of the couch potato idiom just by looking at the picture? A couch potato is a popular expression in American English so it's worth learning.
Couch potato: A very lazy person who sits on a couch watching television all day.
Notes: A couch is another word for sofa. A potato is a big, round, solid food. It's heavy, not light, so it's easy to imagine a potato not being able to move very easily.
Couch potatoes barely move, unless they are reaching for the remote control to change the tv channel. Couch potatoes also often eat unhealthy foods (e.g., chips or sweets) while watching television. They are often considered unhealthy and overweight as a result of being lazy and not moving around.
Please note that we don't use this phrase to talk about people sitting at the computer. It's specifically used for people sitting in a comfortable chair or sofa watching television for long periods of time.
Final note: Did you notice that the plural of potato is potatoes (not potatos)!
