Incident in which you take a dump, and the toilet splashes you back in perineum. This is different from a regular bidet in that it's the toilet water that's splashing you, not a directed tap.
As a rule, this nearly never happens at home, and it frequently happens when you're forced to use a stall with overtly nasty waters or after you've already urinated.
person one: I'm a little worried. I had to use the portajohn at the airshow, and it gave me a spontaneous bidet.
another term for a station wagon, mini-van, or any other kind of vehicle that is targeted at the "family" demographic(also M.A.V.)
"Tactical advantages aside, the M.A.V. is top of the line for the holy warrior troop transport manufactured by the Church of Latter Day Saints Military Industrial Complex. Also great for family trips...to heathen lands."
