Explanation

A scam is a sneaky or dishonest plan that's meant to con someone. A diet scam, for example, falsely claims that people will lose weight if they buy special pills or drinks.

You can also use the word as a verb: "His evil plan was to scam people into buying fake tickets to the baseball game."
