I don’t think you listened to the same audio analysis as me. He exited his truck and was reacting to the weather. Hence, ‘COLD’.
If you start listening early enough, the dispatcher tell Z to keep an eye on “him”.
So when TM moves away from the truck Z gets out of the truck to “keep an eye on him”. He complains that “It’s F cold!”
Dispatcher asks if he’s (out of the truck) following him.
GZ says that he is. And she replies “You don’t have to do that!” (Get out in the cold rain)
Others have taken the entire thing out of context to manipulate it.
I listened to several analyses of the tape but I heard ‘punks’ before I saw any of them. The analysis I just linked to pretty much rules out a hard ‘d’ sound at the end of the word. In any case you can believe whatever you want to. Doesn’t matter to me.
