Fouled up to unimaginable dimensions. Something to do with Canadian ingenuity (or lack thereof). Canadians are not bad people, and a lot of them are very smart. But sometimes, some of them do things that can be very Canucked.
The last owners of this house made an ice-hockey rink in the winter out of their backyard. Come spring, the entire backyard was Canucked.
This particular Canucked individual believed that putting flaming decals on his compact late 1990s coupe would make it travel faster.
After Joey and Alisha hit that weed, they passed out for 2 hours and their entire lives were Canucked.
