Rusty Motor

The act of defecating between one's breasts and then rocking your head from side-to-side making a "brrr" sound, similar to a motorboat.

Guy: "Yeah last night I gave Peggy the biggest Rusty Motor I've ever seen!"

Rusty Motorcycle

The Female version of a Rusty Trombone which involves a female getting rimmed while a vibrator is inserted into her vagina mimicking the vibrations of a motorcycle. It is also customary for the giver to push his or her lips together and make motorcycle noises into her anus.

Oh Katie last night David gave me a Rusty Motorcycle ride and it was amazing!

Rusty Motorboat

When someone places their lips in the recently used/dirty butt crack of someone else, makes the "Brrrrr" sound of a motorboat, and shakes their head back and forth very quickly.

SEAN pooped himself a work and didn't have any toilet paper so KELLY gave him a Rusty Motorboat to clean him up.
