A term referring to an object that has been garishly over-decorated, as many Asian countrymendo to their vehicles, for example. Asian travellers are often seen over-dressed with far too much make-up, brand-name apparel, or other tasteless adornments draped/slung over themselves.
This is to be "riced-out".

Man, those tourists are really riced-out....must be from Japan.
