When you break something and
you don't want anyone to know it was you, so you temporarily set it up so that it looks unbroken. This way, when
the next person touches it, they're under the
impression that they broke it, thus setting them up.
Alyssa: So I
accidentally pulled out the rubber thing that goes around the inside of the door on Evan's car, and I couldn't fix it.
Jenna: Oh? Was he pissed?
Alyssa: Well, he wasn't paying
attention, and I knew Jerry was going to be
getting in any second, so I did a temporary set-up and just kinda shoved it back in. Then when Jerry got in, it fell again and Evan flipped his shit at Jerry.
Jenna: Nice.
