Taking a leak directly into a pool, from the comfort of the pool deck when a bathroom or a secluded bush are just steps away. Usually a booze induced act, the topside pool piss is always met with harsh criticisim from angry onlookers who havent had nearly as many keg beers as the subject taking the piss.

Significance is doubled when Tim Tebow is swimming in said pool.
