Indonesian Lawnmower

The act of licking the pubic hairs of another persons anal cavity in a fast, circular motion. It works much better if the person receiving the Indonesian Lawnmower has a very hairy asshole.

D00d, my asshole is so hairy. I'm gonna tell that ho Rachel to give me the Indonesian Lawnmower, and then I'm gonna fart in her mouth.

Rusty Lawnmower Bongo Drum 

When feces accidentally sprays out of the anus during the course of performing a lawnmower and is addressed by tapping it back into the anus, much like beating on a bongo drum.

How'd that orgy go, Max?
Oh, not too well, Horace. I had to administer a rusty lawnmower bongo drum. You see, I got a little wild with my pull on the anal beads and had to bust out my Billie Jean drum beats to quell the flow of ass butter. Thank God my 4-4 timing was impeccable otherwise it may have been much worse.

When you use your lawnmower and everyone else starts mowing their lawn too. Applies for most equipment such as hedge trimmers and weed whackers.

There he goes again, Steve starting up the lawnmower effect.

devil's lawnmower 

The sexual act in which the girl tugs on the man's ball bag so furiously as if she was lost at sea and it's the only motor that will take her home.. often resulting in some form of testicular or scrotal damage or destruction.

YO! LaFawnduh gave me such a good devil's lawnmower last night I had to go to the ER for emergency surgery. Shit was nice!

kill two cats with one lawnmower 

A modern variation on "kill two birds with one stone."

Since you are going to the store you may as well kill two cats with one lawnmower and return the cans.
