How do you tell if a drunk guy is flirting?

You can often tell if a drunk guy is flirting by observing his body language and behavior. Signs may include prolonged eye contact, leaning in closer, playful teasing, or attempting to initiate physical contact. He might also compliment you more than usual or share personal stories in a more intimate manner. However, remember that alcohol can impair judgment, so it's important to gauge the situation carefully.
