Remember when Goldilocks went to the bears house and ate the porridge? One was too hot, one was too cold, and one was just right, etc, etc. Goldilocked (The Goldilocks Effect) is when something/someone is just right.
"Omg dude! I found the perfect burger."
"Yeah! Not too much sauce.. Heaps of cheese.."
"That burger sounds goldilocked as."
you prepare yourself a meal early in the day and refrigerate for later consumption and your roommate/spouse/someone other then you, microwaves it all, eats half of it and puts it back in the fridge rendering it un-edible because it cannot be re-heated twice for fear of food poisoning.
much like goldilocks and the 3 bears (taking wee bites of porridge and not finishing all of it)
oh man! my roomie totally goldilocked my butter chicken and cous-cous!!
