A fascinating being indeed. Mainly nocturnal creatures, although some have evolved into Day-Walkers. They emerge from hiding from your Cousin's shed out back when the sunsets to pillage for supplies. You can usually identify one of these Cro-magnon humans by their lack of front teeth, entire bodies covered in sores and scabs, and missing minimum 1 digit on either hand. Forget rational communication with these things. They stammer with unintelligible rhetoric that usually relates to Seth Rollins being their favorite WWE wrestler, the one time They had to “bitch” slap their step dad or finally...they are at the local corner store walking around aimlessly in the parking lot.

Tweakers are among the most resilient animals known, with individual species able to survive extreme conditions that would be rapidly fatal to nearly all other known life forms, such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation.

A person that is under the influence of methamphetamines and is in the middle of three projects at the same time none of which will ever be completed.

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.
