When a racer is so bad that he just forgets the road and drives on the grass, like a lawnmower
A wheeled device with a specifically crafted blade designed for cutting grass. Usually has 4 wheels and is pushed along like a shopping trolley, though sometimes they are small, automated 2 wheel machines, and in some cases are much larger and have a seat for riding on, for especially large lawns. The medium ones are often characterised by having a very sudden and forceful yanking of a cord to start the motor, or sometimes the noise they make.
I went out on the weekend and bought a new lawnmower
A word, that can be used to replace the word ”d isabled”, if you don't want to use it.
"This geezer is a real lawnmower!"
Whilst having intercourse in missionary position, the male or female penetrating forcefully rips out the receiving ends pubs, causing blood to drip down toward their vagina, they are usually screaming in pain. The penetrator rubs their fellatio in the blood and reinserts it. The act is usually done on siblings.
"aye man my sister and I tried the Mississippi lawnmower last night, it was amazingly rough."
When you keep talking after a joke doesn't land or nobody gets a subject, and you keep sputtering nearly nonsensical words until the conversation just dies out. Usually a pretty numbing process.
Dude, stop talking. You're lawnmowering my brain into mush.
