look up any word, like the eiffel tower:
The calculated or deliberate folding of toilette paper into a rectangular napkin, designed to ensure maximum fold usage and minimum breach, to be used after a bowel movement. Most commonly used to prevent shit stains.
"During my morning bowel movement I make an Ass Serviette to ensure maximum folds for maximum space usage".
"I hate it when the tp shreds so I make an Ass Serviette".
