Bung Squirts
The spray that shoots out one's ass following an enema. The effect is sometimes replicated as a college prank or by scat freaks. They jam a garden hose up their ass on low pressure until 'full', then release the hose from their anus. Upon release brown shitwater shoots out of the person's ass up to twenty feet.
Jason took the hose out of his ass covered Dave in Bung Squirts.
