When you're sitting on a small toilet and you start to piss, the piss sprays back on you. Only happens for boys, or toilets with no water for girls eg: planes.
"The hotel in Romania had such a fucking small toilet bowl, pissing was like Poseidon Surfing.
"Any time I take a shit, Poseidon always decides to go surfing!"
