Riding A Semi

To have a half erect penis.
Riding a semi is often used in public to tell someone without revealing it to everyone.

Dude, I'm riding a semi right now.

So at the party I was grinding on this chick, but I started to ride a semi and had to get out of there quick.

Riding the Bus With My Sister

When you do or say something that makes you seem retarded. From the Hallmark Hall of Fame movie of the same name starring Rosie O'Donnell in which she plays a "challenged" person who, surprisingly, rides the bus with her sister. What could have been a touching portrayal was ruined by the fact that she spent the majority of the movie screaming and acting like an insane monkey rather than a noble portrayal of a person with mental handicaps. So really, you are acting more like an insane monkey than a retarded person. Can be shortened to Riding the Bus.

"Do you really think you should wear leggings under your skirt? It's a little Riding the Bus with My Sister."

or

"Don't talk so loud in the movie theater. It makes you too Riding the Bus With My Sister."

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.
