pineapple shower

to masturbate. Basically to "prepare to shower all your jizz". It is a lot more convenient to masturbate and jizz all over yourself before you shower so you can wash it off but try to drink at least 2lt of pineapple juice 3 - 4 hours before and you will find that it is fun to jizz on your girl and it shall smell and taste like pine juice. Or in a girls case... I don't know maybe they just like to do it before they get in the shower, which is extremely sexy for some reason.
