As I understand it, it’s a single item of a cheesy corn snack. So there apparently exists a snack called “Cheese Puffs”, which are corn-based with powdered cheese covering them. Where I live, Cheezels and Twisties would probably be the closest equivalents.
The “unit” refers to having just one of them. One twisty or one cheezel, or one puff.

That is way too region specific
