Spanish PaluegoA tiny bit of food that's stuck between your teeth that you fish out with your tongue and eat afterwards.

This is a word that's widely used but hasn't been accepted by the RAE (Royal Spanish Academy) yet. A paluego (n) is a piece of bread or food that gets stuck between your teeth and is usually visible when you talk or open your mouth, that you try to fish out with your tongue or a toothpick. Some people eat them and some spit them out but the ongoing joke that coined this word is that it isn't an accident but rather a way to save the last bite of a great meal for later. It was difficult to find a source but right [here](http://usuarios.multimania.es/alasonceenlaplaza/diccionario.htm) is a dictionary of slang words that lists the word 'paluego'.
