Assume the position
Assume the position is a command that instructs a person to prepare themselves for receiving corporal punishment on their buttocks by assuming a defined spanking position. The command is typically used in the context of a formalized chastisement, most notably in the context of fraternity and sorority spanking. In some fictional contexts, such as the film Dead Poets' Society, it also appears in a school setting but it is not known whether this occurred in real life. Anecdotal evidence suggests that in real life the phrase "Bend over" was more the norm, just as in the UK and the British Commonwealth.
The typical position to assume is bent over, with their hands holding onto their knees or ankles. The chastisement given is usually either a caning (such as the classic "six of the best") or a paddling.
Schoolboys assume the position on command.
