sphincter yoga
through breathing and a yoga-like technique, an individual battles to remain in control of the muscles in their anal sphincter and prevent the effects of diarrea. Often practiced as a result of drinking non-bottled water, while travelling in a foreign country.
in constrained circumstances such as travelling on public transport where the only toilet is extremely unsanitary, and in fact, someone has dumped on the floor rather than in the toilet, and, desperate to go to the toilet due to the effects of diarrea or more generally prairie dogging, one would practice sphincter yoga to avoid having to go to the toilet at that time
