Tweek Trap
A huge scary pile of precariously balanced clutter that is unconsciously created by a tweeker while conducting a desperate search for that bag of dope they think they lost somewhere. A real-life version of Jenga.
I went to Todd's room in the Tenderloin to borrow a bike tool, but when he reached in to grab it, his entire tweek trap came crashing down, leading to extensive injuries. But he found his bag!
