It originated from the 7th season of the CBS show Criminal Minds, when due to the network causing casting chaos and poor writing, a Pasta Party was hosted at a chracter's house, which everyone attended being smiley and happy despite the episode being full of character confrontations and drama. The Pasta Party served as the end of all this drama, cutting short any potential exploration of the conflict.
This trope is also referred to as putting a spaghetti bow on things.
