Popularized by Trailer Park Boys in the 2000s, if not well before

We called em darts when I was in highschool back in the 90s.

I don't remember darts as much on TPB... the phrase "Corey, Trevor, two smokes, let's go" stands out.

Another Trailer Park Boys classic: "That's the way she goes"

As a Nova Scotian I can tell you it was present before 2000s... at least 90s.

Apparently originated in Australia, though it is definitely an established usage in Canada. I seem to recall hearing that usage in Vancouver in the 90s.

Darts an old one. At least since my parents age.

In southern Ontario a dart is also called a bogey

"Dart" is absolutely still used. "Eh bud. Can I bum a dart from ya?"

Throw me a dart, yeah?
