Sandal Master 

The son of David Larson, an Olympic swimmer. Sandal Master is always seen wearing sandals, (or chancletas) no matter what occasion. He also cannot be as athletic as his father, due to a golf cart accident long ago.

One does not simply see Sandal Master without sandals.

Sand Rhino 

Any large woman found in Southern California deserts. Often found drinking Coors Light as if they needed it. Skanky clothes are very common. Sand rhinos hibernate in Glamis and Ocotillo Wells in winter. Also see "Superstition Mountain Goat"

The only thing worse than a Glamis sand rhino is a Fabtech lift kit.

"Hey Jeff! Come here! I just gave Mary an Alabama Sand Storm. Doesn't she look cute?"

An expression used to signify a menial or fruitless task; frequently to be preformed by someone not of sound mind or full capacity.

Giving money directly to a hopeless alcoholic to help him improve his situation is like pounding sand down a rathole.
