The word 甩掉 is formed by combining the character 甩, which depicts the action of swinging or flinging something away (originating from the idea of throwing or discarding with force), with the character 掉, which means to fall or drop. Together, they create a vivid sequential image: first, the act of swinging or throwing (甩), and then the resultant state of that thing falling off or away (掉). This visual and conceptual combination evolves naturally into the metaphorical meaning of "to get rid of" or "to ditch", as if one physically swings something off so that it drops away.
