If someone has their legs up in stirups gettin' ye 'ol annual & they suddenly surprise their OB-GYN with a wretched stream of explosive diarrea.

This condition is worsened when said patient sees no problem with coating their physician with a think sticky coat of leftover chinese & cake, but instead says "oops. a little bout of diarrea." It is even better when you overhear this phone conversation at work.
