Mgem is a very widely used english slang term. Thought to be made in Philadelphia, Pennsylvania. It can be traced back to Zuri Reed of Masterman Laboratory and Demonstration Middle and High School, where it has become immensely popular with the popular denizens. However the true founder(s) of the word is disputed as both Ms. Reed and another fine young woman, Maya Holliday. It is unknown whether they made it together or one of them created it. There are many uses of the word. Usually involving yelling it when you hear something strange or something that appeals to one's self. Examples would be if someone used a very long word. Someone fluent in the dialect would yell out, "geeeeem!!" It is pronounced as umjuhm. Roots of the word are most likely Arabic or Swahili. Possibly deriving from the Zulu tribe's saying of how proper someone is. They would use this as they are ashamed of people who are snobby or arrogant. The saying itself is usually used in conjunction with similar phrases/sayings such as; "I'm mad!" and "I'm upset!" Usually also hand clapping is involved before, during, or after the act. It is widely used by the inner-city youths residing in less-affluent neighborhoods. Translated to simple English, the above statement means that it is mainly used by persons of African American or Black descent. This saying is also verbally related to "yo" or "fuck" because it is an interjection, this means that it can be used randomly and mean absolutely anything or absolutely nothing. This is one of the peculiar mysteries surrounding the saying, as many older usually white people have trouble comprehending the advanced, complicated meanings of it. Because of this many teachers in the school regard the phrase as a "stupid slang term" or a "distraction to the class." It has actually been conclusively proven that the exchange of slang between children to young adults during school develops communication skills and social abilities. Although it can be considered one just as many other slang terms are, mgem is not considered an official word in the English language. Contrary to this, many protesters have been trying to get Merriam-Webster to publish it in their dictionaries. Another commonly used slang term created by the genius minds of Ms. Reed and Ms. Holliday would be "Aye Shama", however it is not as mentioned. This is because it is actually Swahili but rather than inventing it, these women have introduced it to the English-speaking world.
