How it's used
This is the vocabulary for when something, or someone, isn't hitting right.
“You already know not to be posted on the opp block.”
Where it comes from
Origin: Street slang, GTA rap scene. It's tied to Toronto's music and sports culture more than to a specific immigrant-language root — see our "from the block to global" section for how that side of Toronto slang spread.
