As a thinking man, I’ve always found the phrase “Legs up to her neck” very problematic and not a little creepy. If you take it literally, this is what the object of your desire looks like.
She’d look freakish. With no torso, she would lack the necessary organs for life. She would die, like a terrible experiment by a deranged scientist. Her body would flap onto the floor, like a terrified fish out of water, gasping through the lungs she didn’t have, dying there and then. A sad end.
I don’t want a woman like that. I want a woman with an actual body, who is alive.
