People who are paranoid, delusional, uneducated, and covered with oozing chemical scabs and ulcers due to the acute abuse of methamphetamine. They eventually eat scabs from one another that contain the meth that their body can't dispose of, just to catch a cheap thrill. MMMMM....MMMMMMMMM!!!

 Get the tweakermug.
Get the tweakermug. A person who does Crystal Meth. They talk very fast all the time. You're lucky to get a word in with a serious tweaker. They do obsessive projects ranging from, taking a TV set apart, to cleaning a tile floor with a tooth brush. Not finishing anything is common. The thing about meth is that some people have done so much, that even when they quit, they are so damaged that they retain all the characteristics of a tweaker. Ruined for life.
