Walla Walla Waffle Cone

The act of defecating in the shower and smashing the turd into the drain (using feet or hands) until it aquires the grid pattern of the drain. Can be admired and then mashed further until the turd disappears or it can be left behind to be discovered by the next person to use the shower.

Bob got tired of having to use a communal shower so he left a Walla Walla waffle cone behind to convey his displeasure with the situation.
