poo-turn 

When one initially goes to urinate only to realize the pressure applied is pushing feces dangerously close to exiting the anus, requiring a quick turnaround into the sitting position.

Phenomenon is almost solely observed in males, although is occasionally practiced by females in hardcore porn.

It was quite embarrassing having to make a poo-turn from the urinal to the stall at the office.
