The act of hovering over a toilet while you crap, and spray-dusting the whole top of the porcelain and/or wall.
I'll never step foot in this bathroom again until we find out who keeps hovercrafting.
Adj. : I went into the stall after Larry and immediately knew he had hovercrafted; as the seat, back and wall were covered in crap.
Another term for dry-humping.
My virgin girlfriend would allow nothing but hovercrafting with jeans on.
