Can't tell if you're taking the piss haha.

Now you listen here young whipper snipper! Why, in my day....

Yup. Australian here. Is what we call em.

That's the predominant one in Canada too, at least in my experience.

Goes with a Chipper Shredder (Woodchipper), sure there's probably other things named the same way.

I'm trying to spread that term here in the SE US. Everyone looks confused so I say "string trimmer". "you mean weed eater?"
