c.1410, "crouch on the heels," from O.Fr. esquatir "press down, lay flat, crush," from es- "out" (from L. ex-) + O.Fr. quatir "press down, flatten," from V.L. *coactire "press together, force," from L. coactus, pp. of cogere "to compel, curdle, collect" (see cogent). Slang sense of "nothing at all" first attested 1934, probably suggestive of squatting to defecate. The adjective sense of "short, thick" dates from 1630. Squatter "settler who occupies land without legal title" first recorded 1788; in ref. to paupers or homeless people in uninhabited buildings, it is recorded from 1880.
