I don't know if you know the comics Astérix. In this comic, the fish seller sells horribly rotten and smelly fish, and always hurls fish to Roman faces when they say it smells, and everyone fights with rotten fish.
They don't throw them, they hurl/contorquent them, as there's a nice rotation before punching the faces.
But also, hurl: "to throw something with a lot of force, usually in an angry or violent way". This definition was taken from https://dictionary.cambridge.org/dictionary/english/hurl and is the way hurl is being used in this sentence.
