How about 霉国 or 靡国 or 幂国?Based on the way things are going it will soon be 没国. Hell, the last one actually sounds like 美国, but how a English speaker half-fluent in Mandarin would pronounce it.China should change the Chinese name for US to "米国"/"阿米利卡和州国". If Americans protest, tell them there is international precedent.
