where the hell are you?Very informal and rude. มึง is a vulgar form of “you,” and วะ adds a rough, emphatic tone. Use only with close friends who are comfortable with this language, or in confrontational situations.
TH: มึงอยู่ไหนวะ รออยู่ตั้งนานแล้ว
EN: Where the hell are you? I've been waiting forever.
