Pronounced bee-AHN-coh. n. A liar or deceptive person; one who exaggerates to the point of ridicule; a
swine. One who plots schemes, unsuccessfully. Adj. Tricky; fake. Derives from Italian for white or clear (English
cognate is "blank"). Likely, the idea is that though something appears to be there, it's really non-existent or false, similar to
a mirage.
