porcelain cruise 

A mini office vacation. Feeling tired? Have that after-lunch-coma? Take a porcelain cruise! The act of locking oneself in a bathroom stall for 20-30 minutes in order to take a quick nap.

After that heavy lunch, I'm exhausted. Think I'll stop off for a porcelain cruise to relax for a while. Hope no one else comes to stink up my little vacation!

Porcelain Cruise 

When one does his/her business on a toilet, often taking quite long.

Guy 1 walks into washroom: It smells horrible in here!

Guy 2: Sorry, I just took a porcelain cruise.
