The Splinter Cell 

The art of Splinter Cell-ing involves entering a cubicle and graciously performing a dump, without touching the surrounding toilet floor or the toilet itself. This can be performed as a simple one-person challenge, or be used as a practical joke by remaining off the floor undetected until the next user of said cubicle enters and the surprise is released.

Jake: I just used the toilet, and felt a dripping on my head, I looked up to see Sam Fisher himself about to shit on my head
Steve: That's the best performance of The Splinter Cell ever!
