Sentinel Beach Resort

An audible sigh coming immediately after plunking down on the toilet seat before a particularly loud dump. Typically preceding a shot across the bow and very awkward for one’s neighbors in the restroom. Origin unknown but perhaps an ironic reference to the initial sense of tranquility and peace felt by missionaries, anthropologists and other visitors to North Sentinel Island in the Bay of Bengal before hearing the initial volley of arrows.
It was bad enough my dad and had to use adjoining shitters at the rest stop on the way home but when I heard his Sentinel Beach Resort I knew I only had seconds to cover my ears before he opened fire.
