“Piss on the fire and call in the dogs”

To “piss on the (camp)fire and call in the dogs” is an alleged cowboy saying for quitting time. The saying has been cited in print since at least 1969 and has been used by many Texas speakers.
 
Since at least 1998, to “piss on the (camp)fire” has also meant to “rain on someone’s parade” or “cause a fuss” or “upset the apple cart.”
