Get the shit shy mug.
bowel movement that does not want to get out when one is sitting down taking a shit, thus giving the perception that the shit is too shy to leave the rectum.

It is usually straining, time consuming, and inconvenient to push out and deal with.
Boss: What is the deal Thomas? Late for the third time this week!

Thomas: (Nervous and with no eye contact)Sorry boss, i was at home with a case of the shy shits.

Boss: (grabbing Thomas' shouler facing him)Well dont we all.

Both laugh
