look up any word, like columbusing:
 
1.
A large ring of feces exuded onto the rim of a toilet bowl so that the next person to sit on the toilet sits in a pile of shit. The word gets its name because the coil of poop resembles a large donut, and in Spain people eat their own shit. Most people will notice a huge coil of shit around a toilet bowl, so this is best done around drunk people or the retarded.
I just Spanish Donuted that n*****!
