The act of defecating in a shower head of one whom you are in opposition, with the intention of said person taking a shower full of shit.

**MUST HAVE LOTS OF TIME TO PULL OFF THIS HIGH LEVEL MANEUVER**

Procedure:
1. Unscrew shower head
**for smaller shower heads you may need to utilize a pastry bag filled with fecal matter**
2. Fill shower head with fecal matter using either the conventional method or aforementioned pastry bag
3. Replace shower head leaving no evidence behind.

(for added effect, use a creative garnish of your choice or use in conjunction with the Upper Decker)
