A method of clandestine public urination by men. Done by dropping to one knee while wearing shorts and urinating through the leg opening of the kneeling leg.

This is often done while pretending to do something else, like checking tire pressure on the side of the road.
Jerry Collins was caught on camera doing the Mexican kneel right before the start of a Tri-Nations match between New Zealand and Australia.
