When you bite into something hot and cheesy, such as pizza or a sandwich, and the cheese layer slides off and smacks your chin and throat causing minor to severe burns.
Dude, that was some good pizza, but I ate it too fast and got a wicked chinspank.
Chitsa, the shortened form of volchitsa, the Russian word for "she-wolf", typically used as a nickname for a lone, mysterious woman. Also a name of Native American origin meaning "fair".
Man1: Who's that chitsa sitting by herself at the bar?
Man2: No clue, but she looks like she doesn't want to be bothered
Man1: I can respect that.
