I got "chest freeze" once and it was fucking weird. I call it that only because of what caused it and because I have never known anything like it or heard anyone else have a similar reaction.

A couple years ago Iwas working as an installer for a wireless ISP, mostly outdoors working on roofs and shit. This was in the summer and we had a helluva time surveying for the signal before we could install the dish and run the cable, hella hot and shit, on our last appointment of the day. We finally get done and leave the site, which was right next to an AM/PM so I stop and grab a couple Gatorades and as soon as I got back in my truck, just slammed one down. Fucker was ice cold and after I took a couple chugs, it was like a donkey kicked me in the chest. It hurt so bad. But only for like 30 seconds, like a brain freeze headache but in my chest. Shit was weird as fuck and sucked.
