Any poor soul who has the bad ass luck of growing up in a small depressed desert town in CA or elsewhere who is emotionally addicted to CRYSTAL METH. They will kill and die for it, and can never be cured. They will want it every day for the rest of their lives. They start by doing lines, then smoke it, and eventually they graduate to "slamming" using needles. At this time, they never want to see anyone, unless they are tweeking. They are afraid of everything, except death. All of their friends are parolees, and they aint shit until they have been to prison at least once. They steal everything in sight, draw sexually explicit pictures, talk shit, disapear for days or even weeks, will physically assault the people they love, slash their own wrists and arms. They will lose up to 100 pounds in a few years. They will have spent all of their money and lost any job they might have once had. They are unemployable. They hate themselves. They will spent 5 to 40 hours straight beating off and sticking things up their asses. Some will steal panties from the apartment dryers and wear them. They will eventually accomplish self fellatio! Anything is possible with speed!!!

A person who spends countless hours performing repetitive tasks while high on amphetamines or methamphetamines. Usually they hide during the day, away from the public because of the schizophrenic state and horrible complexion caused by days of sleep deprivation and not eating.
