Etymology
Origin of underhanded
Explanation
Use the adjective underhanded to describe someone who plays dirty tricks, like a cheating poker player or a manipulative classmate. It would be underhanded to spread gossip about your opponent during a student council election, just as it's underhanded for a business owner to pay herself more while laying off workers.
