Cincinnati Lawn Mower

A situation where a brother and sister are engaged in a session of 69. At some point (sometimes unintentionally) both parties braces become entangled in the other party's pubic hair, leaving each member no choice but to forcefully detach each member's pubic hair while still entangled in their braces. hence; the name lawn mower. (see:Cincinnati Wool Teeth)

Named after Cincinnati, the location of the first documented case.

Mother: Brian now you and your sister have braces at the same time! How cute!
Friend: Yeah Fitz! How Cute!

Brian: Yeah, whats even cuter is the Cincinnati Lawn Mower we had after the orthodontist appointment.

The Riding Lawn Mower

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.

Russian-Death Mower

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.

I gave Susan the ol' Russian-Death Mower last night. It made her look like a sexy Grinch.
