long-tall-Sally
A particularly tall, thin woman or girl. I know it's crazy, but anytime he goes out on his own or with his friends, I have this irrational anxiety that some long-tall-Sally is going to catch his eye and steal him away from me. I was always a long-tall-Sally as a kid, which I think intimidated some of the boys in my class.
