Mankees are native New Yorkers who have an incoherent sense of importance and ability. They believe that they are the reason why New York City is a great place, even though they haven't made any actual contributions to it. They usually have never left The 5 Boroughs but have a strong opinion that nowhere else is better than New York. They usually think that they are the toughest and smartest people in the room 99.9% of the time. Not specific to any particular demographic, as they come in all shapes, sizes, socioeconomic backgrounds, genders, ages, and races. It is a portmanteau of the words Monkey and Yankee.
One time a chick at the bar told me she could tell that I'm not from New York, and I said thank god because the last thing I want to do is be associated or confused with Mankees. Because we all know Mankees are delusional AF!
Short for man-ankle. Usually used in the context of fashion, specifically when referring to the ankles of a man wearing no socks, and pants which are tailored shorter than is traditional. This style is popular among fashion-forward and/or metrosexual men.
When I was walking to class today, I saw a hipsterguy in übertight pants, flashing some mankle as he walked.
