An extremely lazy coach; posts when practice/game is an hour before practice/game, so half of the team shows up;
-When is your next game? Maybe my team will play you.
-How the hell should I know!!! Mr.______ is such a coach potato.
-Oh, haha, sucks for you.
someone who spends most of their time watching TV and doesn't exercise or have any interesting hobbies. Such a person spends most his/her free time sitting or lying on a coach.
My hubby is killing me; he never socializes. He's never asked me to go out; he's a coach potato.
