Sad Panda Shower
A (usually) sexual act in which one partner performs an act of fellatio on a piece of bamboo while looking sad and the other partner urinates on their head.
That new Japanese exchange student is into some weird stuff! After our sushi date we went back to her place and she made me give her a sad panda shower.
Sad panda shower
A shower in which one is 1. Hungover or 2. Suffering from gastrointestinal distress and lays on the floor of the shower curled up in a fetal position until the hot water runs out.
I was up all night throwing up and only a sad panda shower made me feel better.
