When jizz dries on one's dick tip from beating off the night before. When they wake up the next morning and try to piss, it comes out in two directions like a viper and showers the walls and floors.
After jacking off last night, Teddy tried to piss this morning but instead sprayed the bathroom walls and floor with Viper Piss.
After sex, cum dries in the end of a man's schlong. When he tries to pee, it comes out in two streams like a viper's tongue. It usually happens after a night of drinking.
Dang, I had the viper piss this morning. It went everywhere!
