Guilty pleasure

A guilty pleasure is something that you like to do that makes you feel a little bit embarrassed or bad. It might be something like watching a certain TV show that you think is silly, eating a food that you know is bad for you, or listening to a song that you think other people will make fun of you for liking. Even though it makes you feel a little bit bad, it still feels really good. So you keep doing it secretly and it becomes your guilty pleasure.
