The little shit particles that fly out of you toilet onto the wall after flushing. More common after a full night of drinking Hand sanitizer and Rez wine.

I told my cousin to scrub his Manitoba backwash off the wall.

backwasher

When you work at the Thatcher’s factory and you’re in charge of the process that mixes the cloudy apple and cloudy lemon beverages. Tasking a bit of both in your mouth and spitting it into the big bucket.
