A condition of extremely low bodyfat with superior muscle separation and vascularity. Variations include sliced, cut, and cross-straited.
Slang meaning extreme muscularity.
The end-stage of cutting up - almost all visible body fat is gone, veins show through the skin, and muscle fibers looks like little ribbons draped under the skin. This is a peak condition which is both difficult and undesirable to maintain except just around a competition.
