A style adopted by some young people, normally obnoxious middleschoolers. When you can't tell by a persons style of clothing whether they are aming for the skater, ghetto, prep or scene "look". When all of those looks blend together to create one of the most obnoxious looks: sketto-prene.
Take a look at that sketto-prene 13 year old. "Emo bangs", hollister shirt, juicy couture oversized bag, tight jeans, giant sunglasses, and ecko sneakers. Can tell shes a bitch from looking at her.
