In the movie "Five Easy Pieces" with Jack Nicholson, there is a scene in a diner in which the character played by Nicholson has difficulties ordering food because the waitress that works there is very particular as to what he can order, and she isn't allowing him any leeway with adding or holding anything he can have. This is a link to the scene on youtube:
The sentence I've difficulties with is uttered at the end of the scene (and the video I provided) after the characters leave the diner and are driving in a car.
"Fantastic that you could figure that all out and "lie that down on her" so you could come up with a way to get your toast. Fantastic!"
The only definition for "lie down" which isn't literal( meaning prostrate) I found is:
- to accept without protest or opposition (esp in the phrases lie down under, take something lying down)(Collins Dictionary)
