Shading the poo 

The act of covering the the entire toilet seat with your ass when you take a dump, in order to minimise the spread of stink from your shit.
Lean back on the seat to plug up as much of the hole until you flush.

Note - May require a fat ass.

Guy wanting to take a shit: What are you doing in the bathroom?
Shitter: I'm giving birth to king kong's finger.
Guy wanting to take a shit: No way, I can't smell anything, you must be masturbating.
Shitter: Nah, I'm just shading the poo.
