A swimming pool that has a mixture of vomit in it. This usually results from someone cannonballing into a pool which has floaties already covered in vomit. The act of the cannonball mixes said vomit to thicken the texture of the pool water to a more of a thick, swamp quality.
Oh look, Gary is about to make a swamp pool by cannonballing off of the high dive into the pool which has a bunch of floaties with vomit covered on them. Swamp pool!
* A division of Stingrays Swimming who swim at the ghetto pool with the tent because we don't have a good aquatic center. But we're ten times cooler because that means the week before spring break we play ANIMAL BALL!!!! We are basically like a family, and spend all of our time together. Everyone, even the other Stingrays, wishes they were a West Pool Kid.
