Bum Bath

When a bum or hobo takes a bath in a public restroom sink.

Man I walked into the bathroom and there was a smelly bum taking a bum bath in the sink!

Bum Bath

The art of washing your entire vehicle with the sponge/squegee at the gas pump in less time than it takes to fill your gas tank.

Hey watch this. I'll give my truck a Bum Bath before my tank is full.
