From LWT's "Tarrant on TV" c. 2006. 180 degrees in the title refers to navigation, where 0 degrees is straight ahead and 180 degrees is directly behind.

The 180-degree head turn is popular in horror movies. That's because you
know human heads can't do that. Well, this gentleman's head can. He can turn
his head 180 degrees. It's incredibly creepy to watch. Also, please don't
try it yourself; you could break your neck.
