The name given to punk "drainpipe" jeans when they came into fashion recently. Also called ciggarette pants. They are made of a stretchy material and get slimmer near the ankles. Usually worn by girls but indie/emo/scene/skater/punk boys also wear them. It should be noted that skinny jeans for boys are looser around the crotch so wearing doesn't make you sterile, as alot of ignorant emo haters claim.
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.
