1 definition by J. M. Lawton

A combination of stupid (see. "stupid") and funny (see. "funny") that describes the event as both idiotic and humourous allowing each to interact together on an equal basis but do not detract from the overall events.
The "pineapple episode" last night of "How I Met Your Mother" was incredibly stunny.
