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.
