When you and your sexual partner are outside in a grassy area doing it doggy style, and the female orgasms, planting her face in the grass and effectively cutting it with her teeth. Process repeats in a new area, and the riding lawn mower is in action.
After they did the Riding Lawn Mower for a few hours, Andy and Vanessa could finally play soccer together on the newly cut lawn.

When you and your partner get on the front lawn fully naked and get into the wheelbarrow position. You then pull their arms behind their back so their face is dragging on the ground. You then insert your genitalia into their genitalia and proceed to spin around like a Beyblade, giving them grass-burn.

A favorite method of torture used by the U.S.S.R in times of war to get confessions out of POWs, the common RLM is mistakenly enforced when a person receives head from a braceface while unshaven. The pubes then tangle into the “barbed wire” of the braces and then get torn out when the metal mouth pulls back. It is unfortunate for both, the receiving getting painful ingrown hairs while the perpetrator gets enough hair in their mouth to donate to “Locks For Love” to make wigs for cancer ridden children.
