Flirting at the bar: Buy them a drink after asking for their permission.

💬 [heißen] changes with the subject: [ich heiße], [du heißt], [sie heißen]. Watch the [ß]: it's still pronounced like a sharp [s].

🇩🇪 [du] is informal. In a bar, it's common faster than in many other situations, but with a stranger it still depends on the vibe.

💬 German questions like this often keep the verb in second place: [Wie heißt du?], literally "How are you called?" You can reuse that pattern with [Wie heißt ihr?] or [Wie heißen Sie?].

🇩🇪 [Wie heißt du?] is informal and can feel direct with a stranger. In a bar it may be fine once you've already started chatting, but opening with it can sound a bit abrupt.

💬 With [ich], [heißen] becomes [heiße]: [ich heiße], but [du heißt]. That [e] ending is a very common [ich] pattern in German.
