a laydown
When a hooker falls asleep on heroin and someone pulls her dress over her face and she still doesn't wake up, and your butt is so wide it looks like it's about to burst.
He pulled the dress over her face and her butt looked like it was about to explode.
She was out cold on heroin, and someone pulled the dress over her face like it was a prank.
That laydown made his butt look like it had a life of its own.
