Combination of "Pringles" and "dingleberry," describing the discovery of ancient Pringles crumbs that fell into your belly button at least a fortnight ago, and which, over time, have hardened around one or more of your belly-button hair follicles.

The ensuing fermentation of said pringleberry leads to a related situation called "belly-button hands," which describe a smell associated with rummaging around your belly button whilst fiddling with said pringleberries.
I've been nurturing a pringleberry since last year's Superbowl. It's time to check in and see if my little buddy is ready to harvest.
