To throw something lightly or casually through the air, or to move something from side to side restlessly.
Origin uncertain; possibly from Scandinavian languages or onomatopoeia. Some sources suggest it may be related to 'tousle' (to make messy). First appeared in English around the 16th century.
Nobody really knows where 'toss' comes from—it might be onomatopoeia (the word sounds like the action), which means you're literally saying a sound-imitation word when you describe throwing something carelessly!
