sup

"Sup" is a very casual way to say "What's up?" or "How are you doing?" People mainly use it with friends, in texts, online, or in relaxed face-to-face chats. It works best as a quick greeting, not as a serious question. If someone says "Sup?", common replies are "Not much," "All good," or just "Sup" back. It sounds friendly, easygoing, and informal, so it usually does not fit formal or professional situations.

"Sup" is an extremely casual greeting that means "What's up?", "How are things going?", or simply "Hello." It is a shortened form of "What's up?" and became widely used in informal speech, especially in text messages, social media, and relaxed face-to-face conversations. It is most common among friends or people who already know each other well.

The power of "sup" is its speed and simplicity. It usually is not a deep question or a formal check-in. Instead, it often works like a quick sign of recognition, a friendly opening, or a small invitation to chat. When you use "sup," you usually show that the mood is relaxed and that the relationship is casual.

Still, context matters. "Sup" sounds natural with close friends, classmates, teammates, or online contacts, but it can sound too casual in professional settings or with someone you have just met. You can think of it as a verbal nod: short, friendly, and not demanding a long answer. The word also has an older meaning as a verb, meaning "to eat supper" or "to sip a drink." That use now appears mostly in older writing or fixed expressions, while in modern everyday English, "sup" is overwhelmingly used as a casual greeting.
