the mile-high club

the mile-high club

slang A humorous term for people who have had sex while traveling on an airplane. He's a rock star—of course he's in the mile-high club. I guess the thrill of possibly getting caught is why people want to join the mile-high club, but just thinking about it gives me massive anxiety.
