a person who spends a lot of time sitting and watching TV
"He’s such a couch potato, he never goes out or exercises."
to improvise or decide as you go rather than following a fix...
to go out and enjoy oneself in a lively and extravagant way
to feel refreshed and healthy again
to remove unwanted parts from something
to experience the same unpleasantness you caused to others
to remain calm and confident under pressure
