Shize and Shower
When a person (male or female) claims to take a shower, but really drops a duece then showers to cover up the stench of the nasty shize they just dropped. This will hide the fact that you are taking a duece.
I was at my girlfriend's house (who lives with 3 other females), and had to drop a duece. Instead of facing the embarrasment of violating her bathroom with my stool, I went with the 'ol shize and shower move.
