The act of performing a mundane activity whilst your penis is inserted into chiwawa's asshole. This is also a very renowned sport which tests athlete's endurance and speed know as chernobylling racing.
My neighbour peered over the garden fence on sunday and was suprised to see me doing some gardening with a chiwawa hanging off my manhood. My wife took him to the side and simply explained that it was common for me to do a spot of chernobylling while she cooked the sunday roast. He seemed happy with that and was chernobylling himself the following week with a huge smile across his face
