The Aztec Fist Bump is an ancient technique used by Aztecs to, what they believed that ‘cured’ constipation. It’s a procedure that involves making two incisions in the abdomen, then inserting and pressing your fists against the intestines. Then the one preforming the procedure would squeeze an area of the intestine track together with their fist, collapsing that area and forcing any stool in said area to pass down through the intestine. This graphic procedure obviously came with horrible side effects, and sometimes even resulted in death. But it was believed that doing this would massage and re-shape your intestine walls, so future stools would not get clogged up as they have in the past.

Today, it is used as a sexual move, but has been majorly scaled down and de-intensified. Most modern acts include using your fists to rub the pressure points located near the intestine and massaging the area of constipation to help stool pass through the body quicker so that they may take part in sexual acts using said stool.

1) Sexual position wherein both male and female are laying back facing each other, either in a scissor position or the females legs bent over the males. The penis must be semi-flaccid to bend properly when inserted into the vagina. The thrusting comes from a rapid succession of punches that contact the base of the penis and may even incorporate grazing of the vulva.

2) how you'd picture two paraplegics going at it
