Idioms are an essential part of English. You can come across them everywhere: from daily life to playing video games, reading books or watching films and TV shows in the original. Learning to use common idioms and expressions will make your English sound more native. Let’s take a look at such an idiom “it takes two to tango". It's well known that you can't dance the tango without a partner. This dance is about pairwork and cooperation. There are two meanings of this idiom. The first one is certain actions or activities can't be performed alone – they need two people to participate. The second one is both people involved in a situation are equally responsible for it. Where can we see this idiom? Here's an example: the video game "It takes two". As you see there is only the first part of the idiom in its title but it still conveys the original meanings of the idiom: 1) cooperation. It's a co-op game and it doesn't have a single-player option; 2) two people are responsible for everything
