Super-deformed. In anime and manga, when a character is drawn cartoonishly short, about 3 heads high and has deexagerated limbs (i.e. having mitt-like hands, or long stubs for arms). Characters are often shown super-deformed when characters get in comical situations. Often used interexchangibly with chibi, though technically, they're twoi separate, yet similar things.
