a largely popular style of jeans worn mostly by the junior high, high school, and college age groups. they fit snugly around the waist and are tight around the thighs and calves, tapering down to the ankle. for guys they are a little looser in the crotch area. they were originally worn only by emos, skaters, punks, etc, but now 99% of the population owns at least one pair. however, they really only look good on about 3% of the population. short people, for instance, generally look even shorter when wearing skinny jeans. if you are tall and want to look shorter, wearing skinny jeans will not usually work. they're kind of complicated in that way.
short person: I wish I could wear skinny jeans, but they make me look even shorter than I already am!
tall friend: really?? maybe I should try them! I hate being so tall!
short person: no, the don't work like that.
tall friend: aww, man. that sucks.
