The act of inserting a string of anal beads into a girl, or guys anus. Once the string is fully inserted with just enough to hold onto hanging out, place your foot on the ass and yank out the string of beads like you are starting a lawnmower. You should hear a sound like a motor trying to start that ends with a scream.
Honey, I could really use the lawnmower.

She said I couldn't make her scream, so I gave her the lawnmower.

(v.) Overzealously removing anal beads from one's ass, as in pulling the start cord of a lawn mower, which may often times result in the loss of bowel control.
Instead of plopping them out one at a time as one is supposed to as is proper anal bead etiquette, he lawn mowered her corn hole. To which she replied, "Fuck me in the shit!", and so he did.
