“There was a pause. For a moment I thought she had left the computer. But then she started typing again. She wanted to know if I knew she was a TS girl. A TS girl? What on earth was a TS girl?”
“I've also known TS girls that lacked the adequate training or job skills needed to perform as a woman, or to attain the degree or status of transition they seek merely because they can't pass or find meaningful employment in their chosen gender.”
Used other than figuratively or idiomatically: see TS, girl. (A girl who has a medical condition, such as Turner syndrome or Tourette syndrome, which is initialized "TS".)
