Showberryness

The particular flavour of shock, shame, guilt and revulsion experienced when you go to sit on a public toilet expecting the kiss of cold plastic, and find it pre-warmed by a pair of unfamiliar buttocks.

Showberryness only ever applies when sharing a strangers second hand bum warmth in a cramped cubicle comes as a complete shock. Showberryness is always spiced with a degree of surprise.

The degree of showberryness experienced is directly proportional to the heat of the toilet seat, from an almost imperceptible reaction to a lukewarm / borderline cold seat, to barely suppressed nausea caused by a recent volcano arsed occupant.

Although showberryness is usually a fleeting sensation, a 'flashback' variant is not uncommon if you discover who you caught showberryness off soon after the event.

Disambiguation:
If you hang around in puplic toilets waiting for strangers to vacate cubicles so you can kiss cheeks at one remove, then you either live somewhere very cold and have developed a commendable survival technique, or you're fucking perverted. Neither of these examples can be classed as true showbberryness.
