Definition: the quadrangle that occurs when
A) there is a huge hunk of cake sitting in your refrigerator calling your name and trying to convince you to eat it before it goes bad
B) you want to eat THE WHOLE THING, but are quite aware that THE WHOLE THING contains a bazillion calories
C) you know that your mom will be disappointed and hurt if you avoid temptation by just throwing the darn thing away
D) you go ahead and eat it anyway *sigh*
At least I only ate half THE WHOLE THING. I had to share with the husband (but I did steal some of his frosting).
