Dicky Wick

When a male sits down onto an unfamilliar toilet to defacate, and his junk hangs down into the water. It is most commonly occuring in toilets that are overfilled for whatever reason, as standard design specs for toilets try and avoid this.
Even rarer is the low hanging ball to water contact. Both forms of Dicky Wick are generally unappreciated and a total boner-kill.
If it is unavoidable, care must be taken to properly clean the affected area or you will end up with a form of Shit Sniffies.
