Taking a shit while simultaneously flossing. Usually done in the morning as a way to multi-task before work or right before bed.
Robert: Man, I thought I was definitely going to be late to work today.

Joe: How do you get ready so fast in the morning?

Robert: Dude, shlossing saves me about 10-15 minutes.

Joe: You're sick.
