Elephante Waterfall

The act of filling up a water truck with elephant semen and having it drive in front and spray the semen all over the road coating everyone and everything in sight. Then having another heavy truck drive behind it splashing all puddles of semen to coat unsuspecting pedestrians and cars alike.

So me and my fellow construction workers loaded up a water truck to perform an elephante waterfall. We are still pending court chargers.
