Manesia (noun) - forgetting who a man is even if you have been introduced before to him several times. This happens mainly because men tend to dress similarly in a uniform of untucked striped shirts, jeans, and new balance sneakers. Also there is not a lot diversity of facial hair or haircut style, so it may be difficult to differentiate this guy from others. This condition can affect both men and women, but primarily women. A good way to ward off manesia is for men to obtain a personality, be charming and gracious. European accents help as well.
