@ZophaiRoberts,
Hi Zophai, Colon irrigation refers to two very different things, one medical, one agricultural.
The medical meaning is when anyone ranging from a quack upwards, lays you on one side and does their best to fit a full length garden hose up your poopie.
The hose is connected to a nearby fire hydrant, and the resulting whoop is recorded and sold on to burglar alarm companies.
The agricultural meaning is when a farmer is attempting to grow colonic cucumber, which we all know need moist soil conditions.
Irrigation methods vary, from mechanical pumps and narrow ditches directing the water to the plants, down to the cheapest method which involves waterproof saddle bags, a male donkey and two bricks.
Hope this helps.
