where surrender and origami both begin, depending on the room you're in

means To bend something over on itself so one part lies against another, or to give in and quit — as in a card game or an argument.

from From Old English 'fealdan,' to bend or double over, with deep Germanic roots (compare German 'falten') and a likely cousin in the Latin '-plicare' family that gives us 'ply' and 'fold' words across Europe. The card-game sense — to drop out by laying your cards down — is a much later figurative turn, and the 'sheep fold' meaning of an enclosure is actually a separate Old English word ('falod') that just happens to look the same.
