Yi Ma

"Yi Ma" can refer to a few different things, depending on the context. However, one of the most common interpretations is in relation to the Chinese term “姨妈” (yímā), which translates to "aunt" in English and is often used colloquially to refer to a woman's menstrual period. In this context, "Yi Ma" is a euphemism that some women use to discuss menstruation in a more casual or less direct manner.
