Excessively short trousers resulting in the exposure of ankles, and in extreme cases, calves.

This is a phrase largely equivilent to fucked up or screwed up. It roughly means "in a state of disarray" and is commonly used in the phrase "to jack someone/something up". In some cases, the meaning may be slightly altered by the fact that to get "jacked" can mean to be struck or injured.

Derogative term for trousers worn too short (approx 1-3 inches above the shoe), often with white socks underneath making the jack-up more obvious.
