the shape of consensus reality, held together by four equal lies called sides.
means a square is a quadrilateral with four equal sides and four right angles, and slang for someone allergic to spontaneity.
from from latin exquadrare, to make square, via old french esquarre; the geometric sense predates the personality insult by centuries, though both describe rigid conformity to right angles.
