Computer programming term, stands for "MODIFIED UNTIL NO GOOD", meaning someone applied so many 'fixes', that it stopped doing what it was supposed to...

Later, programmers told new guys it stood for "Mung Until no Good", a recursive loop, and watched their heads explode trying to figure it out...

Speaking as a former paramedic, it has NOTHING to do with dead or pregnant fluids.

A type of Bean

The mung bean is the seed of Vigna radiata which is native to India. Mung beans are commonly used in Chinese cooking. Germinated mung bean sprouts (usually sold simply as 'bean sprouts') are stir fried (usually with ingredients such as garlic, ginger, spring onions or salted fish pieces to add taste) as a vegetable accompaniment to a meal. Uncooked bean sprouts are used in filling for Vietnamese spring rolls. Mung beans are also used to make a sweet soup, served either warm or chilled.
