Skante is a slang term for crystal meth. A skante warrior is a person who has evolved from over usage of crystal meth. They gain supernatural powers, akin to a vampire, except instead of blood, they need more skante. They can tell if someone is carrying skante on them and will attack them on sight. In the more evolved forms, they can harvest skante from other skante warrior's blood. They most basic skante warriors attack in packs, with the most evolved on being the leader
Man 1: What happened to Fred after the party? Man 2: Oh, he became a skante warrior. He looks like a alligator with all those scabs. Man 1: Hey, I kept some meth from the party. Wanna try it? Man 2: Bro, you crazy?!?!? Fred and his pack can smell that shit! Man 1: Oh shit, here he comes. Run bro!!! *gunshots and stabbing sounds*
This is Westcountry slang dating back to before the First World War. Skates are very slippery fish and the name was applied to people who had slippery natures in that they were untrustworthy, would try to avoid giving information or were just not very likeable. The use of the name expanded to include people who were wheeler dealers or people who do a lot of ducking and diving but no actual work. The name is disparaging but at the same time may hold just a hint of reluctant admiration. It is, however, a warning as a skate has no conscience and is totally unscrupulous and untrustworthy. The term is believed to have been used extensively by the British armed forces and was used to describe someone who was a slippery customer, fishy and who avoided their share of the work.
