A sixty second timer one graciously receives via your body when a massive shit is ready to be released.

Being at or near a toilet when timer has begun is highly recommended. Anyone who has seen explosive diarrhea splattered on the walls of a fast food chain bathroom stall has beared witness to a blown or neglected sequence.

At T minus 10 seconds you basically have time to remove your belt and pants at which point you must be pointing into the toilet with your anus or risk a meltdown or massive cleanup.
