Shame donut
A donut you leave in the bag while breaking off pieces and sneaking them into your mouth.
I had an egg white flatbread and coffee followed by a chocolate-glazed shame donut.
Donut Shame
The quickly fading shame you feel for eating more donuts than you should be it 1 or 12. It is quickly fading as you reach for another donut.
Jean E. did not believe Donut Shame was a real affliction, until she caught herself at the wrong end of a baker's dozen.
