Get the German Shower Curtain mug.
German Fan Shower; When the dominant male stands behind a generic fan, which is blowing at it's highest settings. The female is kneeing down in front of the fan as the male jizzes straight into the fan blades, showering the females face and seeps into her scalp.
Dominant Male "Hey baby!, wanna do German Fan Shower tonight?".

Female " Yeah baby!, get me moist right in the face!".
