Fresh hook

Used in Southern Canadian cities such as Toronto to refer to a fresh one-liner or half-bar from the start of a song. Especially when the chorus forms the hook or contains the title of the song and is used ironically to ridicule someone.

"You saying you 'Started from the bottom' fam? Now you just poor over there too!"
A heckler in the crowd: "Ohh! He hit you with that fresh hook!"
