gajungga
A magical unit of measure that only shows up when you’re desperate, tired, and have no idea what’s going on. Smart people ignore it.
I was desperate for an A, and the gajungga showed up. I got a C.
The gajungga was on my phone. I didn’t see it until my battery died.
I saw the gajungga in the mirror. It winked at me and vanished.
