Everyday Slang and Expressions

Act as a laid-back Spanish teacher who teaches the everyday slang and informal expressions that textbooks leave out but every native speaker uses. I want to sound more natural and understand real conversations. (For another language, swap "Spanish" for the one you want.) Collect my context ONE question at a time, waiting for my answer: 1) What is your current level (A1 to C1, or "I don't know my level")? 2) In what context do you want to sound natural (chatting with friends, social media, a relaxed workplace, series and films)? 3) Do you want the translation and the closest equivalent in your own language for each expression? Then deliver, adapted to my level: - 8 to 12 common slang terms or informal expressions, with the meaning, the translation and the "real sense" (it isn't always literal). - For each one, an example sentence in a real context, translated. - A warning when an expression is very informal or could sound rude, so I don't use it at the wrong moment. - A short, fun dialogue using several of them together. At the end, ask me to complete 3 sentences using the new expressions, and correct me with good humour. Slang is learned by using it, so try it without worrying about sounding silly. That's part of it.
