Layer caking 

The act of several people excreting in a enemy or rival's toilet.The (multiple) excretions are continuous and are,at no point until completely finished, to be flushed. Instead, 'layers' are only separated by toilet paper. The end result - which,incidentally, can be expanded by 'icing' or 'finishing touches'- should resemble a (multi)layer cake.

Benny: Hey?!! WTF someone flushed away the layer cake.

Connor: Dont worry. Lets layercake bührers bathroom tommorow again when he is not at home, so the smell can spread.

Sameer: Homeboys, ya layer caking again?
