Threw something carelessly or forcefully, or gave up on something.
From Scottish/Northern English dialect 'chuck' meaning to throw, possibly onomatopoetic (mimicking the sound). Entered wider English in the 1600s.
The word 'chuck' might actually be onomatopoetic—it sounds like a throwing motion—and what's neat is that onomatopoeia works differently in every language, so what sounds like a 'chuck' to English speakers sounds like something completely different to speakers of other languages.
