scanyonaero 

The act of squatting and defaecating on a woman's genitalia. Can be administered by a man or woman.

The 's' is taken from 'scat' as in 'scat porn'. Canyon meaning a loose vagina and 'airo' is the aerodynamic position the donor squats in to deliver the scanyonairo.

After giving Emerald the scanyonaero, Benny threw her a towel and said 'clean yourself up or I will punch you in the ovaries'.
