The middle seat for the backseat passenger that no one wants to sit in was referred to aff I’m sorry,sectionals as the “sissy seat”. Whenever we would take a trip back in the 60s and 70s everyone wanted a window seat. Usually, three people could sit in backseat. Everyone would claim a window and the one who did not set in the “sissy seat”.
“I’m sitting by the window, I’m not sitting in the sissy seat.“
