A person fueled by crystal meth who enjoys both tweaking and quacking. This would be twacking. When a twacker reaches the
peak of their high, they will both indulge in a number of repetitive
useless projects that never get finished tweaking and sit around talking shit on the latest "enemy of the week" quacking. The "enemy of the week or
weak!" is the twacker who happens not to be present in the room that night and will soon be replaced by somebody in the room who is absent from the gathering the next week.
He starts the night smoking his
pipe and starts talking shit about her who. We can be sure next time she is present and he is not, he will be the subject of
the shit talk! Once he is high and project time comes around - he then spends the rest of the night taking apart his car engine with euphoric passion to somehow turn it into a 2000 Honda Accord Version of the Knight Rider! He eventually becomes agitated with the project as he starts coming down. The car is left in pieces for his
parents to pay a mechanic for fix. He has spent the night twacking, and the next night providing funds allow, he will engage in exactly the same behavior - different
people, different project, perhaps. But SAME ROUTINE!
