Screaming black one 

n. Waste material discharged from the anus after a heavy nights drinking and a hot curry. So named by the horrible screaming that follows the sun hot monster that bursts from your behind.

Jesus wept! That screaming black one felt like I was having my anus broiled.

backscreening 

When one inserts a finger into their anus when constipated to retrieve feces that may be stuck and relieve themselves.

"Candice decided she would try backscreening in the shower again"
