"What goes around comes around" is an English idiom that means a persons actions, whether good or bad, will often have consequences for that person. It is used to say that if someone treats other people badly, they will eventually be treated badly by someone else. The phrase suggests that the universe will eventually balance things out and that people will ultimately get what they deserve. The idiom can also be used to mean that things that go out of fashion later come back into fashion. In Spanish, the equivalent expression is "lo que siembres, cosecharás" or "donde las dan, las toman".
