Derived from the root 'manchego' - a Spanish cheese that is also a divine tapas restaurant in Santa Monica, CA. Also - A pet nickname for someone you love with all your heart.
A "house rule" when you are playing Risk and run out of Infantry, (worth 1), but have calvary (worth 5) and artillery (worth 10). Therefore, you have to manipulate "Manchange" with your adversary. When desperate not to "over bet" on a territory you may loose, you can negotiate trades, even (1 for 1) or "rough trade" (3 for 5) or (7 for 10).
Dang, I'm in a pinch, I need manchange, can we trade a canon and a horse for 10 men?
