beanie wash is a function performed by that old toothless hag that can't even afford dentures. This lady can be seen at your local truck stops and at any certain deserted street corner. She may look 60 but is actually only 40. Twenty years older than age looked is a given. She has led a hard life and will perform beanie wash's for anyone. The beanie wash it's self is the gurgling of one's balls in her toothless mouth. Similar to a good tea baggin.
