To throw something carelessly or with force; to discard or get rid of something.
From Scottish dialect, possibly related to Old English 'chukken' or from the Choctaw word 'chuck.' The word entered wider English use in the 1600s.
The word 'chuck' is so casual and dismissive that it's interesting how it's used in cooking ('chuck it in the pot')—showing how informal language often spreads from one meaning to completely different contexts as people adopt it.
