ham·mer n.

A particularity difficult and gnarly trick performed on a skateboard, the emphasis being on the sickness, as opposed to grace or flair of its execution. Usually down or over a large obstacle, more often than not, sets of stairs and handrails, often switch and at great risk to the skateboardist.

Origins: Popularised and derived from "Hammertime" (MC Hammer), to Hammer (verb), and then to noun, e.g. a Hammer is the product of said ‘Hammertime’ (to ‘go off’, ‘come up’, ‘kill it’ or ‘bust out’).

This meaning of Hammer is promoted most vigorously by Jim Greco. Although once a staple of the 'Hesh' community, Hammers now transcend all hesh/fresh barriers, as the documentation of such Hammers is closely linked with making mo' money though incentives and sponsorship, and translates seamlessly into the philosophy of mainstream rap.

Simply put, an attractive girl can be referred to as a hammer. If the aforementioned female is unbelieveably attractive, she can be called a jackhammer or sledgehammer, accordingly. A place where several hammers coexist can be refered to as Hammer City, or Hammerville, USA.
Your sister is a hammer, but your mom is a sledgehammer (usually said with a pelvic thrusting motion).

You gotta go with us to that bar next week, it's Hammer City over there.

I've never seen her before but she must hail from Hammerville, USA.
